Description

Technical Field

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

[0002] Petroleum is an important resource. Crude oil is a viscous brown liquid that is widely used in industry. Generally, before oil is mined, an oil sampling device is needed to sample and test the oil. For example, in the patent number "CN220270913U" and the patent name "A Petroleum Sampling Device", when in use, the connecting piece is connected with a rope, and then the oil sampling device is hoisted into the oil exploration well to be sampled, so that the bottom column slowly sinks into the oil. When the oil overflows the oil inlet, the oil enters the connecting groove from the oil inlet and flows into the oil storage tank. Then the electric push rod contracts and drives the retaining ring to move up to block the oil inlet. Then the staff pulls the rope to lift the oil sampling device out of the oil exploration well. When the sampling experiment is to be carried out, the electric push rod is controlled to extend and push the retaining ring down to open the oil inlet. However, the above structure still has the following problems in actual use:

[0003] When the above structure samples oil, when the oil overflows the oil inlet, the oil enters the connecting groove from the oil inlet and flows into the oil storage tank. However, the sampling amount is fixed, which makes it inconvenient to control the amount of oil sampling, thereby reducing its scope of application and low practicality.

[0004] Therefore, we proposed a controllable oil sampling device that can solve the above problems well. Utility Model Content

[0005] The utility model aims to provide a controllable amount of petroleum sampling device to solve the problem raised by the above background technology that the sampling amount in the current market is fixed, which makes it inconvenient to control the amount of petroleum sampling, thereby reducing its scope of application and low practicality.

[0006] To achieve the above object, the utility model provides the following technical solution: a controllable amount of petroleum sampling device, comprising a main body, a counterweight block is welded to the lower end of the main body, and oil inlets are arranged on both sides of the main body, and the oil inlets are connected to the main body;

[0007] It also includes: a servo motor is bolted to the upper surface of the main body, and a driving gear is fixed to the output end of the servo motor, and the left end of the driving gear is meshed with a tooth block, and the tooth blocks are evenly spaced on the right side of the lifting rod, and the lower end of the lifting rod is fixed to the disc, and a connecting rod is slidably connected in the middle of the disc, and the lower end of the connecting rod is fixed to the floating ball, and the upper end of the connecting rod passes through the upper surface of the main body and is fixed to the pointer, and a scale plate is set on the left side of the pointer, and the lower end of the scale plate is fixed to the upper surface of the main body.

[0008] Preferably, two groups of oil inlets are provided.

[0009] Preferably, a sealing ring is bonded to the outer side surface of the disc, and the outer side surface of the sealing ring is tightly fitted with the inner wall of the main body.

[0010] Preferably, a limit block is arranged above the floating ball below the disc, and the limit block is fixed to the inner wall of the main body.

The specific contents are as follows:

[0015] (1) The oil drives the float ball to float upward, which in turn drives the connecting rod upward, which in turn drives the pointer upward, so that the pointer points to the scale plate. Through the setting of the scale plate, it is convenient to observe the amount of sampling, so as to facilitate the control of the amount of sampling, thereby improving the scope of application of the device and improving practicality;

The setting of the limit block is used to limit the disc, thereby preventing the disc from completely falling to the bottom of the main body, thereby leaving a certain space for the float to prevent the disc from crushing the float, thereby ensuring the normal operation of the float;

[0018] (4) By rotating the ring, the ring drives the linkage gear to rotate together through the external teeth, thereby driving the fixed screw to rotate, so that the fixed screw can be screwed into the ground, thereby achieving the overall fixation of the device and improving the stability during sampling;

[0030] Embodiment 1: In order to solve the problem that the amount of sampling proposed in the prior art is fixed, which makes it inconvenient to control the amount of oil sampling, thereby reducing its scope of application and low practicality, the following scheme is disclosed, including a main body 1, a counterweight block 2 is welded at the lower end of the main body 1, and oil inlets 3 are arranged on both sides of the main body 1, and the oil inlets 3 are connected to the main body 1; it also includes: a servo motor 4 is bolted to the upper surface of the main body 1, and a driving gear 5 is fixed to the output end of the servo motor 4, and the left end of the driving gear 5 is meshed with a tooth block 7, and the tooth blocks 7 are evenly spaced on the right side of the lifting rod 6, and the lower end of the lifting rod 6 is fixed to the disc 8, and a connecting rod 11 is slidably connected in the middle of the disc 8, and the lower end of the connecting rod 11 is fixed to the floating ball 12, and the upper end of the connecting rod 11 passes through the upper surface of the main body 1 and is fixed to the pointer 13, and a scale plate 14 is arranged on the left side of the pointer 13, and the lower end of the scale plate 14 is fixed to the upper surface of the main body 1, and two groups of oil inlets 3 are arranged;

[0031] The main body 1 is placed in the crude oil, and the counterweight block 2 is arranged to facilitate the lower layer of the device as a whole. Then, the servo motor 4 is started, so that the servo motor 4 drives the driving gear 5 to rotate. The driving gear 5 rotates and meshes with the gear block 7, so that the lifting rod 6 is lifted and lowered. The lifting rod 6 drives the disc 8 upward, so that it generates suction, so that the oil can be sucked into the main body 1 through the oil inlet 3. When the oil enters the main body 1, the floating ball 12 can be lifted. The floating ball 12 is lifted, so that the connecting rod 11 slides upward. The connecting rod 11 moves, so that it drives the pointer 13 fixed on the top to point to the scale plate 14. Through the scale plate 14, it is convenient to observe the amount of oil sampling, thereby improving the scope of application of the device and improving practicality.

[0032] Embodiment 2: A new technical solution is added on the basis of Embodiment 1 to prevent the disc 8 from crushing the float 12, thereby ensuring the normal operation of the float 12.

The setting of the limiting block 10 is used to limit the disc 8, thereby preventing the disc 8 from completely falling to the bottom of the main body 1, thereby leaving a certain space for the floating ball 12, preventing the disc 8 from crushing the floating ball 12, and thus ensuring the normal operation of the floating ball 12;

[0034] Embodiment 3: Different from Embodiment 2, this embodiment realizes the overall fixation of the device, improving the stability during sampling.
