DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments: Example

[0028] See also Figure 1-9 A gasoline storage detection sampling device comprises a mounting ring frame 1 inserted into a feed hole 39 of a storage barrel 2, an extension tube 3 vertically extending into the storage barrel 2 is fixed at the center of the mounting ring frame 1, a plurality of limit wedges 8 are radially slidably mounted on the side wall of the mounting ring frame 1, an adjusting ring plate 35 is threadedly connected to the mounting ring frame 1, a locking assembly for driving the limit wedges 8 to move toward the storage barrel 2 is mounted on the adjusting ring plate 35, a sampling barrel 15 is vertically slidably mounted in the extension tube 3, a piston disc 16 is sealingly slidably mounted in the sampling barrel 15, an extension column 20 extending to the outside of the sampling barrel 15 is fixed on the piston disc 16, A lifting tube 7 is fixed on the extension column 20, an oil inlet pipe 14 connected to the sampling cylinder 15 is fixed on the sampling cylinder 15, a vertical scale 5 that slides and extends to the mounting ring frame 1 is fixed on the sampling cylinder 15, a limiting sleeve 21 is fixed on the sampling cylinder 15, a positioning component for limiting the position of the sampling cylinder 15 is installed on the limiting sleeve 21, a guide cylinder 19 is fixed on the top of the sampling cylinder 15, an unlocking component for unlocking the position of the sampling cylinder 15 is installed in the guide cylinder 19, an extension frame 13 is fixed on the mounting ring frame 1, and an oil discharge pipe 4 for docking with the oil inlet pipe 14 is slidably installed on the extension frame 13 through a sliding component.

[0029] When the device is used to sample the gasoline stored in the storage cylinder 2, the mounting ring frame 1 is placed in the feed hole 39 on the storage cylinder 2, and the extension tube 3 is extended into the storage cylinder 2. At this time, the oil inlet pipe 14 enters the storage cylinder 2, and the mounting ring frame 1 is fixed to the storage cylinder 2 by the provided locking assembly to ensure stability during the sampling process.

[0030] By pulling the vertical ruler 5, the sampling tube 15 and the oil inlet pipe 14 can be driven to move vertically. With the help of the scale on the vertical ruler 5, the depth of the oil inlet pipe 14 extending into the storage tube 2 can be accurately grasped, so that the gasoline at a specific depth position in the storage tube 2 can be accurately sampled.

[0031] The positioning assembly of the device includes a positioning wedge 18 slidably mounted on a limiting sleeve 21, a right-angle triangular groove 17 for the positioning wedge 18 to be inserted into the inner wall of the extension tube 3, and a push spring 29 is fixedly connected between the positioning wedge 18 and the limiting sleeve 21. The positioning assembly also includes a connecting column 22 slidably mounted on a guide cylinder 19, and the end of the connecting column 22 away from the guide cylinder 19 is fixed to the positioning wedge 18.

[0032] When the sampling tube 15 moves downward relative to the extension tube 3, the positioning wedge 18 can be inserted into the right-angled triangular groove 17 at the appropriate position. Under the elastic pushing action of the pushing spring 29, the positioning wedge 18 is stably connected to the extension tube 3, so that the vertical position of the oil inlet pipe 14 can be flexibly adjusted and timely positioned, thereby ensuring the stability of the depth position of the oil inlet pipe 14 and accurately sampling the gasoline at a specific position. By pulling the lifting tube 7 to move vertically upward, the lifting tube 7 drives the piston disk 16 to move vertically upward relative to the sampling tube 15 through the extension column 20. At this time, the gasoline in the storage tube 2 is drawn into the sampling tube 15 through the oil inlet pipe 14 to achieve sampling.

[0033] The unlocking assembly of the device includes an unlocking wedge 23 fixed to the connecting column 22, the unlocking wedge 23 is located in the guide cylinder 19, a lifting frame 24 is vertically slidably installed in the guide cylinder 19, an unlocking slide column 26 abutting against the unlocking wedge 23 is fixed to the bottom of the lifting frame 24, and an arc groove 28 is provided on the unlocking wedge 23 to abut against the unlocking slide column 26.

[0034] By pulling the pull rod 6 upward, the lifting frame 24 can be driven to move upward. At this time, the unlocking slide column 26 on the lifting frame 24 pushes the unlocking wedge 23, and the unlocking wedge 23 drives the connecting column 22 to slide toward the guide cylinder 19, thereby making the positioning wedge 18 move out of the right-angled triangular groove 17. When the unlocking slide column 26 moves to engage with the arc groove 28, the position of the positioning wedge 18 after movement is achieved. At this time, under the buoyancy of gasoline, the sampling cylinder 15 automatically floats upward, causing the oil inlet pipe 14 to move upward, which is beneficial for the subsequent docking of the oil inlet pipe 14 with the oil discharge pipe 4 to obtain the gasoline sample inside the sampling cylinder 15. Example

[0035] See also Figure 1-9 On the basis of Example 1, in addition, a limit stopper 25 located below a lifting frame 24 is fixed to the inner wall of the guide cylinder 19 of the device, a pull rod 6 passing through the lifting tube 7 is fixed on the lifting frame 24, and a push block 27 is fixed to the top of the pull rod 6.

[0036] In the process of moving the lifting tube 7 upward to extract gasoline into the sampling tube 15, when the upper end of the lifting tube 7 pushes against the push block 27, the push block 27 drives the pull rod 6 to move upward, thereby driving the unlocking component to transmit, so that the positioning wedge block 18 moves out of the right-angle triangular groove 17. The above process realizes the continuous extraction of gasoline, unlocking of the sampling tube 15 and floating of the sampling tube 15, which greatly improves the gasoline sampling efficiency and the convenience of operation.

[0037] The locking assembly of the device includes a stop plate 9 fixed on the mounting ring frame 1, a limit wedge block 8 is slidably sleeved on the stop plate 9, and a connecting spring 34 is fixed between the limit wedge block 8 and the mounting ring frame 1. The locking assembly also includes a rotating collar 32 rotatably mounted on the adjusting ring plate 35, a push plate 11 is fixed on the rotating collar 32, a transmission groove 10 is fixed on the top of the limit wedge block 8, an inclined surface 33 is opened in the transmission groove 10, a push plate 11 vertically corresponding to the inclined surface 33 is fixed on the rotating collar 32, and a rotating rod 31 is fixed on the adjusting ring plate 35.

[0038] When the mounting ring frame 1 moves downward and extends into the feed hole 39, the wedge surface of the limiting wedge block 8 abuts against the storage tube 2, so that the limiting wedge block 8 moves toward the mounting ring frame 1 and compresses the connecting spring 34. Finally, the non-wedge surface part of the limiting wedge block 8 abuts against the mounting ring frame 1, and the stop plate 9 abuts against the top of the mounting ring frame 1, thereby preliminarily limiting the position of the mounting ring frame 1.

[0039] The rotating rod 31 drives the adjusting ring plate 35 to rotate, so that the adjusting ring plate 35 moves downward relative to the mounting ring frame 1, and the mounting ring frame 1 drives the rotating sleeve 32 to move downward. At this time, the push plate 11 on the rotating sleeve 32 slides and abuts against the inclined surface 33, so that the transmission groove 10 drives the limiting wedge block 8 to move in the direction away from the mounting ring frame 1, thereby ensuring that the limiting wedge block 8 is tightly abutted against the inner wall of the feed hole 39, ensuring the position stability of the mounting ring frame 1, that is, ensuring the stability of the device during the sampling process, and improving the sampling accuracy of gasoline.

[0040] The sliding assembly of the device includes a threaded rod 12 rotatably mounted on an extension frame 13, a translation frame 36 is threadedly connected to the threaded rod 12, an oil drain pipe 4 is rotatably mounted on the translation frame 36, a clamping strip 37 that slides through the extension frame 13 is fixed to the side wall of the oil drain pipe 4, a docking sleeve 30 for plugging in the oil inlet pipe 14 is fixed to the oil drain pipe 4, and a positioning arc plate 38 vertically corresponding to the oil inlet pipe 14 is fixed to the docking sleeve 30.

[0041] During the floating process of the sampling cylinder 15, the oil inlet pipe 14 moves up to the highest point and abuts against the positioning arc plate 38. At this time, the axial correspondence between the docking sleeve 30 and the oil inlet pipe 14 is completed, and then the threaded rod 12 is rotated. The threaded rod 12 drives the translation frame 36 to move, and the translation frame 36 drives the oil discharge pipe 4 to move toward the oil inlet pipe 14, thereby achieving a close docking between the oil inlet pipe 14 and the docking sleeve 30. At this time, the lifting tube 7 is pressed down, so that the piston plate 16 moves vertically downward relative to the sampling cylinder 15, so that the gasoline in the sampling cylinder 15 is discharged from the oil inlet pipe 14 and transported along the docking sleeve 30 and the oil discharge pipe 4, which greatly facilitates the acquisition of the gasoline extracted by the sampling cylinder 15.

[0042] In summary, the present invention can adjust the position of the limiting wedge 8 through the locking assembly, so that the limiting wedge 8 moves toward the storage tube 2 inside the feed hole 39 of the storage tube 2, and fix the mounting ring frame 1, ensuring the overall stability of the device when sampling gasoline through the oil inlet pipe 14. At the same time, the sampling tube 15 can limit the position in real time during the vertical downward sliding process, so that the sampling position can be stably limited, ensuring accurate sampling of gasoline at a specific depth. The sampling tube 15 of the present invention can drive the oil inlet pipe 14 to move vertically above the mounting ring frame 1, and drive the oil discharge pipe 4 to move toward the oil inlet pipe 14 through the sliding assembly, and realize the docking of the oil discharge pipe 4 and the oil inlet pipe 14 through the docking sleeve 30. The lifting tube 7 is moved downward to discharge the gasoline sample from the sampling tube 15 for acquisition, which greatly facilitates the gasoline sampling operation.
