Description

Technical Field

[0001] The utility model relates to the technical field of detection and sampling, in particular to a petroleum detection and sampling device. Background Art

[0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as the blood of industry. Petroleum is stored in some areas of the upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. There are two theories about the formation mechanism of petroleum: biological sedimentation oil and petrochemical oil. When sampling petroleum, existing petroleum detection and sampling devices usually require personnel to manually pump air inside the sampler to extract the petroleum into the sampler.

[0003] The currently published patent: CN221280727U, discloses an oil detection and sampling device. The reciprocating screw is driven to rotate by the output end of the servo motor. The reciprocating screw drives the piston through the screw slot and moves up and down in the slide groove through the slider. When the piston moves upward, air is pumped into the oil through the tube body into the device body, so that the oil can be extracted into the device body without manual operation, which improves work efficiency and reduces the workload of users.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: the oil detection sampling device can extract oil into the device body without manual operation when in use, which improves work efficiency and reduces the workload of users. However, after the staff completes sampling, the sampling port at the lower end of the sampling tube is not sealed. When the staff moves the sampling device, oil is likely to drip from the sampling port to the lower side, which not only wastes oil resources, but also requires staff to clean up the oil dripping to the ground. Utility Model Content

[0005] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a petroleum detection sampling device that can solve the problem that when the staff completes sampling and the sampling port at the lower end of the sampling tube is not sealed, the staff easily drips from the sampling port to the lower side when moving the sampling device, which not only wastes petroleum resources but also requires staff to clean up the petroleum dripping onto the ground.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a petroleum detection sampling device, comprising a sampling cylinder and a sampling tube sealing device; two grips are fixedly connected to the surface of the sampling cylinder, and the sampling tube is fixedly connected to the bottom of the sampling cylinder; the sampling tube sealing device comprises a sealing ball, a rotating shaft, a gear, a sliding sleeve, a slider, a toothed plate, a cylindrical block, a pull rod, a sleeve spring and a round ball, the sealing ball is rotatably connected to the inside of the sampling tube, a through hole is opened on the surface of the sealing ball, the rotating shaft is rotatably connected to the inside of the sampling tube, the right end of the rotating shaft is fixedly connected to the surface of the sealing ball, the left end of the rotating shaft extends to the outside of the sampling tube, the gear is fixedly connected to the left end of the rotating shaft, the upper end of the sliding sleeve is fixedly connected to the bottom of the sampling cylinder, the slider is slidably sleeved inside the sliding sleeve, the toothed plate is fixedly connected to the lower end of the slider, the toothed plate is meshed with the gear, the cylindrical block is slidably connected to the inside of the slider, the pull rod is slidably connected to the inside of the slider, the pull rod is fixedly connected to the surface of the cylindrical block, and the sleeve spring is slidably sleeved on the surface of the pull rod.

[0007] Preferably, a piston is slidably connected to the interior of the sampling cylinder.

[0008] Preferably, an electric telescopic rod is fixedly installed on the top of the sampling cylinder, and the output end of the electric telescopic rod is fixedly connected to the top of the piston.

[0009] Preferably, the ball is fixedly connected to the end of the pull rod away from the cylindrical block.

[0010] Preferably, the sleeve spring is fixedly connected to the surface of the cylindrical block, and one end of the sleeve spring away from the cylindrical block is fixedly connected to the inner wall of the slider.

[0011] Preferably, the surface of the sliding sleeve is provided with two cylindrical clamping blocks which are slidably clamped in the interior of the lower side.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In the oil detection sampling device, after the staff loosens the ball, the sleeve spring releases its elastic force and pushes the cylindrical block to slide forward and fit into the interior of the upper side to fix the sealed ball. At this time, the sampling port at the lower end of the sampling tube can be sealed by the sealed ball. When the staff moves the sampling device, oil cannot drip from the sampling port to the lower side, which not only avoids the waste of oil resources, but also prevents oil from dripping onto the ground and causing pollution.

[0025] The staff can move the sampling device by holding the two handles 2 with both hands, and drive the sampling tube 5 to move inside the oil storage tank, and make the lower end of the sampling tube 5 enter the interior of the oil. After the staff starts the electric telescopic rod 3, the output shaft of the electric telescopic rod 3 moves upward to drive the piston 4 to move upward, thereby reducing the pressure inside the sampling cylinder 1. The external atmospheric pressure can press the oil inside the storage tank into the interior of the sampling tube 5, and then discharge it into the interior of the sampling cylinder 1 through the sampling tube 5 to complete the oil sampling.

[0026] The sampling tube sealing device includes a sealing ball 6, a rotating shaft 8, a gear 9, a sliding sleeve 10, a slider 11, a tooth plate 12, a cylindrical block 13, a pull rod 14, a sleeve spring 15 and a round ball 16.

[0027] After the oil sampling is completed, the staff first moves the device upward through the handle 2 and drives the sampling tube 5 to separate from the surface of the oil. Then, the staff slides the pull rod 14 backward through the ball 16. The pull rod 14 slides backward to drive the cylindrical block 13 to slide backward to squeeze the sleeve spring 15. At this time, the sleeve spring 15 gives the cylindrical block 13 a reverse elastic force. The cylindrical block 13 slides backward and moves out of the interior of the lower side 17. Then the staff slides the slider 11 upward and drives the tooth plate 12 to slide upward.

The staff slides the pull rod 14 backward through the ball 16. The pull rod 14 slides backward to drive the cylindrical block 13 to slide backward to squeeze the sleeve spring 15 , the cylindrical block 13 slides to the rear side and moves out of the interior of the lower side 17, and then the staff slides the slider 11 upward and drives the tooth plate 12 to slide upward. The tooth plate 12 slides upward to drive the gear 9 and the rotating shaft 8 to rotate at the same time. The rotation of the rotating shaft 8 can drive the sealing ball 6 to rotate ninety degrees to seal the channel inside the sampling tube 5. After the staff loosens the ball 16, the sleeve spring 15 can release the elastic force and push the cylindrical block 13 to slide forward and get into the interior of the upper side 17 to complete the fixation of the sealing ball 6.
