[0027] Specifically, Figure 1 , Figure 2 and Figure 5 As shown, when in use, the connecting ring 1, the pull rope 11, the static conductive copper wire 13, the movable groove 12, the first connecting block 14 and the second connecting block 15 are provided. When in use, the pull rope 11 can be sleeved with the connecting ring 1 in an open state. After the sleeve is sleeved, the movable groove 12 is rotated to make it threadedly engaged and displaced on the outer walls of the first connecting block 14 and the second connecting block 15, and the position of the movable groove 12 is adjusted upward or downward until the first connecting block 14 and the second connecting block 15 are completely sleeved and overlapped, so that the connecting ring 1 is changed from an open state to a closed state, so as to prevent the pull rope 11 from being detached after being sleeved with the connecting ring 1, and make the connection more firm;

[0028] A pull rope 11 is sleeved on the outer wall of the connecting ring 1, and a static conductive copper wire 13 is arranged inside the pull rope 11 to avoid static electricity when in contact with it and prevent sparks from appearing inside, complying with the requirement of strictly prohibiting fireworks, and making it safer to use.

[0029] Working principle: before use, the upper cover 6 and the bottom tank 8 are respectively threadedly connected and assembled with the tank body 7. According to the different sampling depths, the tank body 7 can be replaced with different upper covers 6 and bottom tanks 8 to complete the sampling operation of oil at different depths inside the oil tank. The upper cover 6 and bottom tank 8 installed in this solution are specially used for sampling and collecting oil products in the upper and middle parts of the oil tank, and a counterweight block 9 is arranged inside the bottom tank 8 to balance the gravity of the overall bottom of the tank body 7 to avoid the phenomenon that the tank body 7 is inconvenient to sink due to the large buoyancy above the oil products. The pull rope 11 is sleeved with the connecting ring 1, and the pull rope 11 is provided with a static conductive copper wire 13, so that the overall anti-static effect is better and the use is safer. The first connecting block 14, the second connecting block 15 and the movable groove 12 are provided between the connecting ring 1 and the hanging rod 2, so that it is easy to disassemble and assemble with the hanging rod 2. When it is needed to be installed by notch sleeve connection during use, the hanging rod 2 can be sleeved with the opening provided on the connecting ring 1. After sleeve connection, the movable groove 12 is held by hand and rotated to make the inner concave thread provided on the inner wall of the connecting ring 1 mesh with the outer convex thread provided on the outer wall of the first connecting block 14 and the second connecting block 15 to complete the up and down transmission, until the opening provided on the connecting ring 1 is sleeved, the overall sleeve connection and shielding of the first connecting block 14 and the second connecting block 15 are completed, so that the connecting ring 1 as a whole changes from an open to a closed position, avoiding the pull rope 11 and the connecting The ring 1 is disengaged, making its sleeve connection more secure, and the opening and closing adjustment is more convenient and easy to operate. After the accessories are connected, the cover groove 4 and the mouth groove 5 are in a snap-fit ​​closed state. When the cover groove 4 and the mouth groove 5 are snap-fitted, the extended snap-fit ​​ball 19 extending through the reserved groove 21 on one side of the cover groove 4 is retracted into the reserved groove 21 by the force of the elastic ring 17 until the position of the snap-fit ​​ball 19 corresponds to the snap-fit ​​groove 20 set on one side of the inner wall of the mouth groove 5. Then it can pop out and snap-fit ​​with it, so that the cover groove 4 and the mouth groove 5 are snap-fitted and closed, and then the sampling equipment is put into the tank mouth as a whole, and the connection is lowered by pulling the pull rope 11 until it contacts the oil product. At this time, the pull rope 11 is stretched to drive the cover groove 4 and the mouth groove 5 to disengage. After the cover groove 4 is subjected to the tensile force, the whole cover groove 4 is lifted up from the inner wall of the mouth groove 5. After the force is applied, the card ball 19 shrinks to the inside of the reserved groove 21 through the elastic action of the elastic ring 17. Therefore, after the card ball 19 is separated from the card groove 20 set on the inner wall of the mouth groove 5, the cover groove 4 and the mouth groove 5 lose their only limiting effect and complete separation. After the cover groove 4 and the mouth groove 5 are separated, the cover groove 4 is pulled up by the pull rope 11 and contacts the top end of the lifting rod 3 for limiting. The oil product smoothly enters the inside of the tank body 7 from the mouth groove 5, completing the sampling process of the oil product. After the sampling is completed, the pull rope 11 is used to cooperate with the lifting rod 3 and the gravity to complete the lifting and removal process of the sampling equipment as a whole from the tank mouth, completing the use process of the petroleum tank sampling device.
