Description

Technical Field

[0001] The utility model relates to the technical field of energy exploration, in particular to an oil detection sampling device. Background Technique

[0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons, which is a viscous, dark brown liquid with a natural occurrence. Petroleum is mainly used as fuel and gasoline, and is also a raw material for many chemical industrial products, such as solutions, fertilizers, pesticides and plastics.

[0003] In the specific industrial production process, because petroleum is a viscous liquid with a relatively large density, when the portable sampling device carried by the sampling personnel is sampling, when the sampling device contacts the surface of petroleum, due to the relatively large contact area of the bottom of the cylinder and the common cylinders are all slender structures, it is easy to cause the device to tip over. At the same time, the sampling device descends slowly in the viscous petroleum liquid, and the sampling efficiency is not ideal. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an oil detection sampling device that overcomes the above technical problems or at least partially solves the above problems.

[0005] The utility model is implemented as follows:

[0006] The utility model provides an oil detection sampling device, which includes a main cylinder, and a sampling mechanism is arranged inside the main cylinder. The sampling mechanism includes:

[0007] A vertical insertion rod, the bottom of the vertical insertion rod penetrates through the bottom of the main cylinder, and a sealing ring that overlaps the bottom inner wall of the main cylinder is fixedly installed on the vertical insertion rod;

[0008] A compression spring, the compression spring is sleeved on the vertical insertion rod, the top of the compression spring is fixedly connected to the top inner wall of the main cylinder; the bottom of the compression spring is fixedly connected to a limiting disk, and the limiting disk is fixedly connected to the vertical insertion rod;

[0009] A frustum ring, the frustum ring is fixedly connected to the bottom of the main cylinder, and the diameter of the frustum ring gradually decreases from top to bottom;

[0010] Insertion legs, the insertion legs are fixedly connected to the bottom of the frustum ring.

[0011] In an embodiment of the utility model, a vibrating mechanism is arranged directly above the main cylinder. The vibrating mechanism includes an installation box, one side of the installation box is movably connected with a driving gear through a bearing, one side of the installation box is fixedly connected with a sliding rail and a fixed column, the fixed column is movably connected with a driven gear through a bearing, and the top of the fixed column is fixedly connected with a fixed strip.

[0012] In an embodiment of the present utility model, a first swing bar is fixedly connected to one side of the driven gear. One end of the fixed bar is movably connected to a second swing bar through a plug shaft. A first slider sleeved on the second swing bar is movably connected to the first swing bar through a plug shaft. One end of the second swing bar is movably connected to a third swing bar through a plug shaft. One end of the third swing bar is movably connected to a second slider located on the sliding rail through a plug shaft. A vibrating rod is fixedly connected to the side surface of the second slider.

[0013] In an embodiment of the present utility model, the first swing bar is fixedly installed on the upper half of the side surface of the driven gear, and the lower half of the side surfaces of the driving gear and the driven gear are meshed.

[0014] In an embodiment of the present utility model, a structure cylinder located directly above the main cylinder is provided on the back of the installation box of the vibrating mechanism, and a fixed double ring is fixedly connected to the bottom of the structure cylinder.

[0015] In an embodiment of the present utility model, the bottom end of the vibrating rod penetrates through the bottom of the structure cylinder and extends to directly above the main cylinder.

[0016] In an embodiment of the present utility model, a limiting ring is fixedly connected to the top of the outer wall of the main cylinder.

[0017] In an embodiment of the present utility model, the upper half of the vibrating rod is an inclined rod and the lower half is a vertical rod, and the rotating shaft of the driving gear of the inserting leg penetrates through the inner wall of the installation box.

[0018] A petroleum detection sampling device provided by the present utility model has the following beneficial effects:

[0019] 1. Through the setting of the sampling mechanism, when sampling, the inserting legs first insert into the petroleum, giving a preliminary horizontal restraint effect to the whole device. As the device further sinks, the frustum ring can also act in a similar principle to a needle inserting action and enter the petroleum liquid, avoiding the situation that the contact area of the lower plane of the device is too large and the device may be toppled due to the large reaction force received at the initial moment of entering the petroleum liquid. When the device reaches the bottom of the petroleum liquid, the vertical inserting rod is pushed up, and the liquid enters the main cylinder to start sampling. Or at any stage after the bottom of the device enters the petroleum liquid, pulling the vertical inserting rod from above can also pull the vertical inserting rod out of the bottom of the main cylinder, and the socket of the vertical inserting rod is exposed at the bottom of the main cylinder, facilitating sampling at any height.

[0020] 2. Through the setting of the vibrating mechanism, after the petroleum liquid enters the bottom of the device, the vibrating rod can impact the main cylinder downward, applying an external force to the top of the main cylinder and improving the efficiency of the device entering the petroleum liquid. At the same time, when the vibrating mechanism is moving, the movement of the vibrating rod is an accelerating impact in one direction and has a smaller acceleration in the other direction. The effect is stronger when impacting downward and gentler when pulling upward, avoiding large-scale vibrations of the sampling mechanism and improving the stability effect of the device.

[0028] Example

[0029] Reference Figures 1 - 4 The technical scheme provides a petroleum detection sampling device, which includes a main tube 1, and a sampling mechanism 2 is arranged inside the main tube 1.

The bottom of the vertical insertion rod 201 passes through the bottom of the main tube 1. A sealing ring overlapped with the bottom of the inner wall of the main tube 1 is fixedly installed on the vertical insertion rod 201. The compression spring 202 is sleeved on the vertical insertion rod 201. The top of the compression spring 202 is fixedly connected to the top of the inner wall of the main tube 1. The compression spring 202 The bottom is fixedly connected with a limit plate 2021, the limit plate 2021 is fixedly connected to the vertical insertion rod 201, the cone ring 203 is fixedly connected to the bottom of the main tube 1, the diameter of the cone ring 203 decreases from top to bottom, and the insertion leg 204 is fixedly connected to the bottom of the cone ring 203. When the device reaches the bottom of the petroleum liquid, the vertical insertion rod 201 is lifted up and the vertical insertion rod 201 is pulled out of the bottom of the main tube 1. At this time, the vertical insertion rod 201 is still inserted at the top of the main tube 1 and will not deviate. The liquid enters the main tube 1 and begins sampling. Or at any stage after the bottom of the device enters the petroleum liquid, pull the vertical rod 201 from the top, and the vertical rod 201 can also be pulled out of the bottom of the main tube 1, so as to facilitate sampling at any height. After the sampling is completed, let go, and under the action of the compression spring 202, the vertical rod 201 is restored to its original installation through the limit plate 2021, so that the bottom of the main tube 1 is sealed. When sampling, the plug leg 204 is first inserted into the petroleum, giving the entire device a preliminary horizontal constraint effect. As the device further sinks, the truncated cone ring 203 can also act as a needle-like action to enter the petroleum liquid, avoiding the device's lower plane contact surface being too large, and the device being subjected to a large reaction force at the initial moment of entering the petroleum liquid. When the device reaches the bottom of the petroleum liquid, the vertical rod 201 is lifted up, and the liquid enters the main tube 1 to start sampling. Or at any stage after the bottom of the device enters the petroleum liquid, pull the vertical rod 201 from the top, and the vertical rod 201 can also be actively pulled out of the bottom of the main tube 1, so as to facilitate sampling at any height.

[0030] Reference Figures 1 - 4, based on the same concept as the above-mentioned Embodiment 1, this embodiment also proposes that a vibrating mechanism 3 is provided directly above the main cylinder 1. The vibrating mechanism 3 includes an installation box 301. One side of the installation box 301 is movably connected with a driving gear 303 through a bearing. One side of the installation box 301 is fixedly connected with a sliding rail 302 and a fixed column 3041. A driven gear 304 is movably connected to the fixed column 3041 through a bearing. The top of the fixed column 3041 is fixedly connected with a fixed strip 3043. One side of the driven gear 304 is fixedly connected with a first swing bar 3042. One end of the fixed strip 3043 is movably connected with a second swing bar 306 through a plug shaft. A first slider 305 sleeved on the second swing bar 306 is movably connected to the first swing bar 3042 through a plug shaft. One end of the second swing bar 306 is movably connected with a third swing bar 307 through a plug shaft. One end of the third swing bar 307 is movably connected with a second slider 308 located on the sliding rail. The side of the second slider 308 is fixedly connected with a vibrating rod 309.

[0031] Specifically, the first swing bar 3042 is fixedly installed on the upper half of the side of the driven gear 304. The lower half of the sides of the driving gear 303 and the driven gear 304 are meshed. A structural cylinder 4 located directly above the main cylinder 1 is provided on the back of the installation box 301 of the vibrating mechanism 3. The bottom of the structural cylinder 4 is fixedly connected with a fixed double ring 401. The bottom end of the vibrating rod 309 penetrates through the bottom of the structural cylinder 4 and extends to directly above the main cylinder 1. The rotating shaft of the driving gear 303 is connected to the output end of the motor inside the installation box 301 through a plug shaft. The driving gear 303 drives the driven gear 304 to rotate. At this time, the driven gear 304 rotates, and the fixed strip 3043 does not move. The driven gear 304 drives the first swing bar 3042 to rotate. The first swing bar 3042 drives the first slider 305 to slide back and forth, causing the second swing bar 306 to swing back and forth, and further driving the third swing bar 307 to swing back and forth. Finally, the second slider 308 slides back and forth, causing the vibrating rod 309 to move up and down in the vertical direction.

[0032] Specifically, a limiting ring 101 is fixedly connected to the top of the outer wall of the main cylinder 1. The fixed double ring 401 includes two rings fixedly connected by a connecting rod. The limiting ring 101 is located between the two rings of the fixed double ring 401. The upper half of the vibrating rod 309 is an inclined rod and the lower half is a vertical rod. The rotating shaft of the driving gear 303 of the inserting leg 204 penetrates to the inner wall of the installation box 301.

[0033] The working process or principle of this oil detection sampling device is as follows: When the device reaches the bottom of the oil liquid, the vertical insertion rod 201 is lifted, and the vertical insertion rod 201 is pulled out from the bottom of the main cylinder 1. At this time, the vertical insertion rod 201 is still inserted into the top of the main cylinder 1 and will not shift. The liquid enters the main cylinder 1 to start sampling. Or at any stage after the bottom of the device enters the oil liquid, pulling the vertical insertion rod 201 from above can also pull the vertical insertion rod 201 out of the bottom of the main cylinder 1, facilitating sampling at any height. After sampling is completed and the hand is released, under the action of the compression spring 202, the vertical insertion rod 201 is restored to its original installation through the limit disk 2021, making the bottom of the main cylinder 1 airtight. Connect the rotating shaft of the driving gear 303 to the output end of the motor inside the installation box 301 through an insertion shaft. The driving gear 303 drives the driven gear 304 to rotate. At this time, the driven gear 304 rotates, the fixed strip 3043 does not move, the driven gear 304 drives the first swing bar 3042 to rotate, the first swing bar 3042 drives the first slider 305 to slide back and forth, causing the second swing bar 306 to swing back and forth, and further driving the third swing bar 307 to swing back and forth. Finally, the second slider 308 slides back and forth, causing the vibrating rod 309 to move up and down in the vertical direction.

[0034] It should be noted that the main cylinder 1 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so no further details will be elaborated.
