Description

Technical Field

[0001] This utility model belongs to the field of oil detection technology, and specifically relates to an improved oil sampler. Background Technology

[0002] In the oil and fat industry, oils (grain oils) are stored in large oil tanks. Inspectors need to take samples regularly to test the quality of the oils. During the oil sampling process, a sampler is needed to enter the oil tank to take the sample. However, most existing samplers require multiple people to work together to complete the sampling, which is labor-intensive and time-consuming. Especially for deeper oil tanks, the operation is more difficult for inspectors and the oil sampling efficiency is low. At the same time, the contact between the hands and the sampling rope during sampling can easily contaminate the oil sample. In order to solve the problems mentioned above, we propose an improved oil sampler. Utility Model Content

[0003] The purpose of this utility model is to provide an improved oil sampler, which has the advantages of being able to lock at any time, convenient and fast sampling, and avoiding sample contamination.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an improved grease sampler includes a hand ring, a C-rod is bolted to the back of the hand ring, a wire guide box is bolted to the end of the C-rod away from the hand ring, a rotating wheel is rotatably connected to one side of the wire guide box, a screw sleeve is embedded in the right side of the wire guide box, a screw rod is threadedly connected to the inside of the screw sleeve, and the left side of the surface of the screw rod penetrates the right side of the inner wall of the wire guide box, a moving block is rotatably connected to the left end of the screw rod through a bearing, a pressure block is bolted to the left side of the moving block, openings are provided at the top and bottom of the wire guide box, a steel wire rope is connected to the middle rope of the connecting frame away from the connecting ring, and the surface of the steel wire rope penetrates the opening and the interior of the wire guide box, and a quick sampling mechanism is provided at the end of the steel wire rope away from the connecting frame.

[0005] The above technical solution replaces the traditional hemp rope with a steel wire rope. The steel wire rope is extended outwards and moves outwards, entering the wire guide box through the top opening. The steel wire rope contacts the rotating wheel, which facilitates the release and retraction of the rope. The rope then extends downwards from the bottom opening inside the wire guide box. When locking the steel wire rope, a screw is rotated. The rotating screw sleeve limits the screw's movement, causing the screw to rotate and move to the left, moving a moving block. This moving block then compresses the steel wire rope, locking it in place. This locking mechanism controls the sampler's lowering position, preventing depth deviations caused by the steel wire rope slipping during sampling, ensuring accurate sampling results, preventing accidental slippage or repeated adjustments, avoiding human contact with the sampling rope, and preventing contamination of oil samples by external substances. In the locked state, no continuous force is required, preventing loss of control due to manual pulling. This allows for efficient single-person operation, reducing the complexity and time costs of multi-person collaboration, and ensuring both sampling accuracy and equipment durability and operational safety.

[0006] The present invention is further configured such that the rapid sampling mechanism includes a pot holder, the pot holder is connected to the end of the steel wire rope away from the connecting frame, the two sides of the inner wall of the pot holder are rotatably connected to a sampling pot, the bottom of the sampling pot is provided with an oil inlet groove, and a ball plug is provided inside the oil inlet groove.

[0007] The above technical solution employs a rapid sampling mechanism. A steel wire extends outwards, causing the kettle frame to move downwards. The kettle frame then moves the sampling kettle. Once the bottom of the sampling kettle contacts the grease, the grease enters the oil inlet trough. The ball plug automatically floats up and enters the left-hand branch at the top of the oil inlet trough. The grease then enters the sampling kettle from the right-hand branch at the top of the oil inlet trough. After sampling, the steel wire rope is retracted, causing the kettle frame and sampling kettle to move upwards. After the sampling kettle separates from the grease inside the oil tank, the ball plug, under the influence of gravity, blocks the opening at the bottom of the oil inlet trough, preventing grease leakage from the sampling kettle. When the sampling kettle enters the oil tank, a one-way valve automatically opens upon contact with the oil layer, reducing the frequency of manual intervention and enabling rapid sampling by a single person. When the valve closes, it forms a physical isolation barrier, preventing leakage caused by kettle shaking during grease storage or transportation, thus ensuring sample integrity.

[0008] The present invention is further configured such that a connecting ring is rotatably connected to the surface of the handheld ring, a connecting frame is welded to the surface of the connecting ring, an outer ring is welded to the front and rear ends of the connecting frame away from the connecting ring, and a rotating block is rotatably connected to the top of the front side of the outer ring at the front end.

[0009] The above technical solution involves setting up a connecting ring. One hand holds the hand ring, and the other hand holds the handle. Rotating the handle around the hand ring causes the handle to rotate, which in turn causes the rotating block to rotate. The rotating block then causes the outer ring to rotate, which in turn causes the connecting frame to rotate. Finally, the connecting frame causes the connecting ring to rotate, allowing the wire rope to be released and retrieved.

[0010] The present invention is further configured such that sliders are welded to the front and back of the movable block, and sliding grooves are provided on the right side of the front and rear ends of the wire box, and the inside of the sliding grooves is slidably connected to the surface of the sliders.

[0011] The above technical solution uses sliders and grooves to limit the movement of the moving block.

[0012] The present invention is further configured such that the oil inlet groove is configured in a forked shape.

[0013] The above technical solution uses a forked shape to limit the movement of the ball plug.

[0014] The present invention is further configured such that a handle is fitted onto the front side of the rotating block.

[0015] The above technical solution allows for easy gripping of the rotating block by incorporating a handle.

[0016] The present invention is further configured such that a rod head is sleeved on the right side of the screw.

[0017] The above technical solution allows for easy rotation of the screw by setting a rod head.

[0018] The present invention is further configured such that the front and back of the hand ring are perforated.

[0019] The above technical solution incorporates a perforated design to facilitate gripping of the hand ring.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model can control the lowering position of the sampler by locking and fixing it, avoiding depth deviation caused by the slippage of the wire rope during the sampling process, ensuring the accuracy of the sampling results, avoiding accidental slippage or repeated adjustments of the sampler, reducing the frequency of personnel contact with the wire rope, reducing the risk of external impurities mixing with grease, and eliminating the need for continuous force in the locked state, avoiding loss of control due to manual pulling, realizing efficient operation by a single person, reducing the complexity and time cost of multi-person collaboration, and ensuring sampling accuracy while taking into account equipment durability and operational safety;

[0022] 2. When the sampling vessel enters the oil tank, the one-way valve automatically opens after the sampling vessel contacts the oil layer, reducing the frequency of manual intervention and enabling rapid sampling by a single person. When the valve is closed, it forms a physical isolation barrier to prevent leakage caused by shaking of the vessel during oil storage or transportation, thus ensuring the integrity of the sample.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4An improved grease sampler includes a handheld ring 1, with a C-rod 2 attached to the back of the handheld ring 1. A wire guide box 3 is attached to the end of the C-rod 2 away from the handheld ring 1. A rotating wheel 4 is rotatably connected to one side of the wire guide box 3. A screw sleeve 5 is embedded in the right side of the wire guide box 3, and a screw rod 6 is threaded into the screw sleeve 5. The left side of the screw rod 6 penetrates the right side of the inner wall of the wire guide box 3. A moving block 7 is rotatably connected to the left end of the screw rod 6 via a bearing. A pressure block 8 is attached to the left side of the moving block 7. Openings 9 are provided at the top and bottom of the wire guide box 3. A steel wire rope 10 is connected to the middle rope of the connecting frame 16 away from the connecting ring 15, and the surface of the steel wire rope 10 penetrates the opening 9 and the interior of the wire guide box 3. A quick sampling mechanism is provided at the end of the steel wire rope away from the connecting frame 16. The traditional sampling rope is replaced by a steel wire rope. For food safety considerations, the steel wire rope is made of food-grade 304 stainless steel, which ensures that the grease is not contaminated during the sampling process. By extending the steel wire rope 10 outward, the steel wire rope 10 moves outward and enters the wire guide box 3 through the top opening 9. The steel wire rope 10 contacts the rotating wheel 4, and the rotation of the rotating wheel 4 facilitates the release and retraction of the steel wire rope 10. The steel wire rope 10 is released downward from the bottom opening 9 inside the wire guide box 3. When it is necessary to lock and fix the steel wire rope 10, the screw 6 is rotated. The screw 6 rotates and moves to the left, driving the moving block 7 to move. The moving block 7 drives the pressure block 8 to squeeze and lock the steel wire rope 10. Locking and fixing can control the lowering position of the sampler and avoid depth deviation caused by the slippage of the steel wire rope 10 during the sampling process, thus ensuring the accuracy of the sampling results.

[0032] refer to Figure 1 , Figure 2 A connecting ring 15 is rotatably connected to the surface of the hand ring 1. A connecting frame 16 is welded to the surface of the connecting ring 15. An outer ring 17 is welded to the front and rear ends of the connecting frame 16 away from the connecting ring 15. A rotating block 18 is rotatably connected to the top of the front of the outer ring 17. By setting the connecting ring 15, one hand holds the hand ring 1 and the other hand holds the handle 21. Rotating the handle 21 with the hand ring 1 as the center causes the rotating block 18 to rotate. The rotating block 18 causes the outer ring 17 to rotate. The outer ring 17 causes the connecting frame 16 to rotate. The connecting frame 16 causes the connecting ring 15 to rotate. This allows the steel wire rope 10 to be released and retrieved.

[0033] refer to Figure 4 The movable block 7 has sliders 19 welded on its front and back sides. The inside of the wire box 3 has a sliding groove 20 on the right side of the front and rear ends. The inside of the sliding groove 20 is slidably connected to the surface of the slider 19. By setting the slider 19 and the sliding groove 20, the movement of the movable block 7 can be limited.

[0034] refer to Figure 1 , Figure 2A handle 21 is fitted onto the front of the rotating block 18, which makes it easy to hold the rotating block 18.

[0035] refer to Figure 3 , Figure 4 A rod head 22 is sleeved on the right side of the screw 6, which allows the screw 6 to be rotated easily.

[0036] refer to Figure 1 The front and back of the hand ring 1 are perforated with holes 23, which make it easy to hold the hand ring 1.

[0037] Brief description of usage: When the external steel wire rope 10 is needed for grease sampling, hold the perforated hole 23 on the hand ring 1 with one hand and the handle 21 with the other. Rotate the handle 21 around the hand ring 1. The handle 21 drives the rotating block 18 to rotate, which in turn drives the outer ring 17 to rotate. The outer ring 17 drives the connecting frame 16 to rotate, which in turn drives the connecting ring 15 to rotate. This allows the steel wire rope 10 to be released and retrieved. When releasing the steel wire rope 10, the steel wire rope 10 moves outward and enters the cable box 3 through the top opening 9. The steel wire rope 10 contacts the rotating wheel 4, and the rotation of the rotating wheel 4 facilitates the release and retrieval of the steel wire rope 10. The steel wire rope 10 is released downward from the bottom opening 9 inside the cable box 3. When it is necessary to lock and fix the steel wire rope 10, hold the rod head 2. 2. Rotating screw 6 limits the movement of screw 6. Screw sleeve 5 limits the movement of screw 6. Screw 6 rotates and moves to the left, driving moving block 7 to move. Slider 19 and slide groove 20 limit the movement of moving block 7. The movement of moving block 7 drives pressure block 8 to squeeze steel wire rope 10 and lock it in place. Locking and fixing can control the lowering position of the sampler, avoid depth deviation caused by slippage of steel wire rope 10 during sampling, ensure the accuracy of sampling results, avoid accidental slippage or repeated adjustments of the sampler, reduce the frequency of personnel contact with steel wire rope 10, and reduce the risk of external impurities mixing with grease. No continuous force is required in the locked state, avoiding loss of control due to manual pulling, realizing efficient operation by a single person, reducing the complexity and time cost of multi-person collaboration, and ensuring sampling accuracy while taking into account equipment durability and operational safety.

[0038] Example 2:

[0039] refer to Figure 1 , Figure 5An improved grease sampler includes a rapid sampling mechanism comprising a jug holder 11, which is connected to the end of a steel wire rope 10 away from the connecting frame 16. Sampling jugs 12 are rotatably connected to both sides of the inner wall of the jug holder 11. An oil inlet groove 13 is provided through the bottom of the sampling jug 12, and a ball plug 14 is installed inside the oil inlet groove 13. The steel wire rope extends outward, causing the jug holder 11 to move downward. The jug holder 11 then moves the sampling jug 12. After the bottom of the sampling jug 12 contacts the grease, the grease enters the oil inlet groove 13. The ball plug 14 automatically floats up and enters the top left branch of the oil inlet groove 13. The grease enters the sampling jug 12 from the top right branch of the oil inlet groove 13. After sampling, the steel wire rope 10 is retracted, causing the jug holder 11 and the sampling jug 12 to move upward. After the sampling jug 12 separates from the grease inside the oil tank, the ball plug 14, under the influence of gravity, blocks the opening at the bottom of the oil inlet groove 13, preventing grease leakage from the sampling jug 12.

[0040] refer to Figure 5 The oil inlet groove 13 is set in a forked shape, which can limit the movement of the ball plug 14.

[0041] Brief description of the usage process: When sampling grease, the steel wire rope 10 is extended to move the pot holder 11 downwards. The pot holder 11 moves the sampling pot 12. After the bottom of the sampling pot 12 contacts the grease, the grease enters the oil inlet trough 13. The ball plug 14 automatically floats up and enters the fork on the top left side of the oil inlet trough 13. The grease enters the sampling pot 12 from the fork on the top right side of the oil inlet trough 13. After sampling, the steel wire rope 10 is retracted. The steel wire rope 10 moves the pot holder 11 and the sampling pot 12 upwards. After the sampling pot 12 separates from the grease inside the oil tank, the ball plug 14 is blocked by gravity at the bottom of the oil inlet trough 13 to prevent the grease inside the sampling pot 12 from leaking out. When the sampling pot 12 enters the oil tank, the one-way valve automatically opens after the sampling pot 12 contacts the oil layer, reducing the frequency of manual intervention and enabling rapid sampling by a single person. When the valve is closed, it forms a physical isolation barrier to avoid leakage caused by the shaking of the pot during grease storage or transportation, ensuring the integrity of the sample.
