[0002] Petroleum testing and sampling equipment plays an important role in the petroleum industry. Petroleum, as a viscous, dark brown liquid, is one of the main targets of geological exploration. During the storage process, due to the deposition and suspension of impurities, the quality of petroleum at different liquid levels varies. Therefore, in order to determine the quality of petroleum at different liquid levels, it is necessary to perform stratified sampling of petroleum in the storage tank.
[0003] However, in existing sampling devices, the sampling bottle needs to be replaced after each sampling, which is a cumbersome and time-consuming process, and the capacity of the sampling bottle cannot be adjusted. Based on this, the present invention is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] Example 1: Refer to Figures 1-5 A petroleum testing and sampling device includes a support frame 1, and further includes: a water storage tank 2 fixedly connected to the support frame 1, a piston plate 32 slidably connected inside the water storage tank 2; a drain pipe 21 connected to the piston plate 32, a one-way valve provided inside the drain pipe 21, and a through hole 22 opened on the water storage tank 2; a first sliding plate 4 and a second sliding plate 5 are slidably connected to the support frame 1, a first blocking block 41 is fixedly connected to the first sliding plate 4, and a second blocking block 51 is fixedly connected to the second sliding plate 5; when the first blocking block 41 and the second blocking block 51 clamp the through hole 22, the piston plate 32 is pushed, and the liquid in the water storage tank 2 is discharged from the drain pipe 21.
[0027] In this invention, the volume of the water tank 2 can be changed by sliding the piston plate 32, and can be adjusted according to one's needs. The distance between the first block 41 and the second block 51 can be adjusted. When there is a certain gap between the first block 41 and the second block 51, the first sliding plate 4 is pulled upward to open the through hole 22, so that the water tank 2 can automatically collect the surrounding oil. When the first block 41 and the second block 51 are clamped together, the through hole 22 is blocked. At this time, the space inside the water tank 2 is a closed space. The one-way valve in the drain pipe 21 can control the water flow from the inside of the water tank 2 to the outside in one direction. When the through hole 22 is blocked, the oil inside the water tank 2 can be squeezed to the outside through the drain pipe 21 by pushing the piston plate 32.
[0028] Example 2: Refer to Figures 1-5 Similar to Embodiment 1, but with a further improvement: a base plate 3 is fixedly connected to the piston plate 32, a limit rod 31 is fixedly connected to the base plate 3, a limit hole 23 is provided on the water tank 2, the limit rod 31 is slidably connected to the limit hole 23, a sliding block 6 is fixedly connected to the base plate 3, the sliding block 6 is slidably connected to the support frame 1, a pressure plate 61 is slidably connected to the sliding block 6, a locking bolt 62 is rotatably connected to the pressure plate 61, the locking bolt 62 is threadedly connected to the sliding block 6, and a sliding groove 11 is provided on the support frame 1. The locking bolt 62 is slidably connected to the sliding groove 11. A counterweight 12 is rotatably connected to the bottom of the support frame 1. A limit post 14 is fixedly connected to the support frame 1. The limit post 14 is slidably connected to the first sliding plate 4 and the second sliding plate 5. A compression spring 15 is fixedly connected to the limit post 14. A lifting bolt 43 is rotatably connected to the first sliding plate 4. The lifting bolt 43 is threadedly connected to the second sliding plate 5. A first lifting ring 13 is fixedly connected to the support frame 1. A second lifting ring 44 is fixedly connected to the first sliding plate 4.
[0029] In this utility model, scale lines can be provided on both sides of the support frame 1 to facilitate the user to determine how many samples can be collected in the water tank 2 when moving the base plate 3. By rotating the locking bolt 62, the pressure plate 61 can be moved on the sliding block 6, thereby controlling the squeezing and clamping force of the pressure plate 61 on the support frame 1. The side of the pressure plate 61 facing the support frame 1 is provided with anti-slip texture. When the pressure plate 61 is in close contact with the support frame 1, the base plate 3 is locked and limited.
[0030] By rotating the lifting bolt 43, the first sliding plate 4 can be moved away from or closer to the second sliding plate 5. The first blocking block 41 and the second sliding plate 5 are in a sealed state. When the distance between the first sliding plate 4 and the second sliding plate 5 is as follows: Figure 4As shown, under normal conditions without external interference, the compression spring 15 will press the first sliding plate 4, causing the first block 41 to press tightly against the through hole 22. At this time, the through hole 22 is in a sealed state, and the elastic force of the compression spring 15 is small, so that when the first sliding plate 4 moves upward, it will not cause the entire device to move significantly upward. When the water tank 2 reaches the sampling position, the first sliding plate 4 is pulled upward, causing the first block 41 to leave the through hole 22. The radius of the connecting rod connecting the second sliding plate 5 and the second block 51 is smaller than the radius of the through hole 22, so the through hole 22 is in a state of connection with the outside, thus enabling oil collection. When the lifting bolt 43 is rotated to move the first sliding plate 4 towards the second sliding plate 5, the first block 41 and the second block 51 together clamp the through hole 22. At this time, the through hole 22 is in a sealed state. By pushing the bottom plate 3 to drive the piston plate 32 upward, the oil in the water tank 2 can be squeezed out through the drain pipe 21.
[0031] A separate rope is connected to the first lifting ring 13 and the second lifting ring 44 respectively. The rope on the first lifting ring 13 is mainly used to control the sinking depth of the entire device. The rope on the second lifting ring 44 can pull the first sliding plate 4 upward so that the first block 41 leaves the through hole 22 to collect oil.
[0032] The counterweight 12 is rotatably connected to the support frame 1 via a rotating shaft. The counterweight 12 serves as a counterweight and also acts as a base. When collecting oil in the water tank 2, the support frame 1 can be rotated to make the water tank 2 and the drain pipe 21 tilt at a certain angle and align with the collection port of the collection device.
[0033] When using the device, the user first rotates the locking bolt 62 to release the pressure plate 61 from limiting the support frame 1, moves the base plate 3 to adjust to the required amount for this collection, and rotates the locking bolt 62 to re-fix it. Then, the user ties the rope to the first lifting ring 13 and the second lifting ring 44, and submerges the device in the oil. When the device reaches the predetermined position, the user pulls the rope connected to the second lifting ring 44 to open the through hole 22 for collection. After collection is completed, the user releases the rope connected to the second lifting ring 44 and pulls the rope connected to the first lifting ring 13 to pull the device up. Then, the user rotates the lifting bolt 43 to clamp and block the through hole 22 with the first block 41 and the second block 51. The user rotates the locking bolt 62 to release the limitation on the base plate 3, and pushes the base plate 3 to squeeze the collected oil into the collection device.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
