[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 4 , Figure 5This utility model provides an embodiment of a sampling device for oilfield exploration, comprising a C-shaped base 1, a separation chamber 3 fixedly connected to the top of the inner wall of the C-shaped base 1, a base 18 slidably connected to the inner wall of the C-shaped base 1, a connecting block 19 slidably connected to the inner wall of the base 18, a second motor 24 disposed at the bottom of the connecting block 19, a plurality of eccentric wheels 20 fixedly connected to the output end of the second motor 24, a plurality of second springs 21 disposed on the inner wall of the base 18, a plurality of third springs 22 disposed on both sides of the outer wall of the base 18, a plurality of limiting blocks 23 fixedly connected to the inner wall of the C-shaped base 1, the bottom of the separation chamber 3 fixedly connected to the top of the connecting block 19, a sampling chamber 2 fixedly connected to the left side of the outer wall of the separation chamber 3 via a pipe, a filter plate 14 slidably connected to the inner wall of the separation chamber 3, a slider 15 fixedly connected to the outer wall of the filter plate 14, and a lifting assembly disposed on the left side of the inner wall of the C-shaped base 1.

[0025] Specifically, the output of the second motor 24 drives multiple eccentric wheels 20 to rotate, thereby driving multiple second springs 21 to move longitudinally and laterally. This generates both longitudinal and lateral forces on the connecting block 19, causing the connecting block 19 to oscillate and accelerate the separation of crude oil and impurities in the separation chamber 3. At the same time, it allows the filter plate 14 to slide, preventing the filter plate 14 from clogging and extending the service life of the equipment.

[0026] Reference Figure 1 , Figure 4 The lifting assembly includes a first motor 13, which is disposed on the inner wall of the C-shaped seat 1. The output end of the first motor 13 is fixedly connected to a connecting rod 25. The outer wall of the connecting rod 25 is rotatably connected to a fixing block 8. The outer wall of the connecting rod 25 is rotatably connected to a limit box 10. The inner wall of the limit box 10 is rotatably connected to a first eccentric gear 11 and a second eccentric gear 12. The second eccentric gear 12 is fixedly connected to the outer wall of the connecting rod 25. The bottom of the fixing block 8 is fixedly connected to the top of the sampling chamber 2. The inner wall of the fixing block 8 is slidably connected to a lifting block 9. The bottom of the lifting block 9 is fixedly connected to a piston 7, which is slidably connected to the inner wall of the sampling chamber 2.

[0027] Specifically, the first motor 13 drives the connecting rod 25 to rotate the second eccentric gear 12. The second eccentric gear 12 meshes with the teeth of the first eccentric gear 11. The first eccentric gear 11 drives the lifting block 9 to move upward, which in turn drives the piston 7 to suck the crude oil from the oil field into the inner wall of the sampling chamber 2 for sampling, saving manpower and improving efficiency.

[0028] Reference Figure 5 Multiple eccentric wheels 20 are rotatably connected to the front and rear sides of the connecting block 19, and multiple second springs 21 are disposed on the outer wall of the connecting block 19.

[0029] Specifically, by setting multiple eccentric wheels 20 in front and behind the connecting block 19, the connecting block 19 is allowed to swing up and down on the inner wall of the base 18 by multiple second springs 21, which facilitates the acceleration of crude oil separation.

[0030] Reference Figure 5 Multiple third springs 22 are slidably connected to one side of the limiting block 23.

[0031] Specifically, the third spring 22 slides on the inner wall of the limiting block 23, causing the base 18 to move left and right, thereby achieving the effect of making the connecting block 19 sway left and right.

[0032] Reference Figure 2 , Figure 3 The outer wall of the slider 15 is slidably connected to the inner wall of the separation chamber 3. The inner wall of the slider 15 is slidably connected to the limit rod 16. The outer wall of the limit rod 16 is provided with a first spring 17. The limit rod 16 is fixedly connected to the inner wall of the separation chamber 3.

[0033] Specifically, by setting a first spring 17 at the bottom of the slider 15, the slider 15 slides along the path of the limit rod 16 on the inner wall of the separation chamber 3, thereby vibrating the filter plate 14, preventing the filter plate 14 from being blocked by crude oil, affecting the working process, and playing a role in maintaining the equipment.

[0034] Reference Figure 1 A water tank 6 is fixedly connected to the top of the inner wall of the C-shaped seat 1. An oil tank 5 is fixedly connected to the top of the water tank 6. The top of the oil tank 5 is fixedly connected to the gas tank 4. The top of the gas tank 4 is fixedly connected to the bottom of the inner wall of the C-shaped seat 1. The outer walls of the gas tank 4, oil tank 5 and water tank 6 are all equipped with flexible hoses that are fixedly connected to the outer wall of the separation chamber 3.

[0035] Specifically, gas tank 4, oil tank 5, and water tank 6 are connected to separation tank 3 via pipelines, and their order is set according to the density of these substances to achieve collection after separation.

[0036] Reference Figure 2 The outer wall of the lifting block 9 is slidably connected to the inner wall of the sampling chamber 2, and the outer wall of the lifting block 9 is rotatably connected to the inner wall of the first eccentric gear 11. The outer wall of the limiting box 10 is provided with a limiting groove, and the lifting block 9 is slidably connected to the inner wall of the limiting groove.

[0037] Specifically, by setting a limiting groove on the outer wall of the limiting box 10, the lifting block 9 slides on the outer wall of the limiting box 10 through the first eccentric wheel 11, thereby driving the piston 7 to move.

[0038] Reference Figure 4 The first eccentric gear 11 and the second eccentric gear 12 are meshed at the tooth ends.

[0039] Specifically, the first eccentric gear 11 and the second eccentric gear 12 are meshed together, and the second eccentric gear 12 transmits power to the first eccentric gear 11, which then powers the lifting block 9 to achieve the subsequent work.

[0040] Working principle: The pressure of the piston 7 of the equipment draws crude oil from the telescopic pipe between the sampling chamber 2 and the separation chamber 3 into the separation chamber 3. Then, multiple second motors 24 drive multiple third eccentric wheels to rotate, thereby driving the second spring 21 to move vertically while the third spring 22 moves horizontally, achieving an oscillation effect, thus accelerating the crude oil separation process. The filter plate 14 is fixedly connected to a slider assembly. Through the cooperation of the slider 15, the limit rod 16 and the first spring 17, combined with the vibration assembly, the filter plate 14 is prevented from clogging, thus maintaining the equipment and increasing its service life.

[0041] The first motor 13 of the sampling device provides power, and the second eccentric gear 12 is fixedly connected to the connecting rod 25. The second eccentric gear 12 meshes with the tooth end of 11, and 11 is fixedly connected to the lifting block 9. The lifting block 9 drives the piston 7 seat to move up and down. The piston 7 sucks crude oil into the sampling chamber 2. The bottom pipe of the sampling chamber 2 samples the oil field, replacing manual labor, saving manpower, and thus improving efficiency.
