Description

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. The definition of "natural gas" that has long been commonly used is a narrow definition based on energy, that is, it refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in the strata.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] like Figures 1 to 6 As shown, the utility model provides a liquefied natural gas sampler, comprising:
[0031] A sampling tank 1, the left end of the sampling tank 1 is fixedly sleeved with an air inlet pipe 2, and the right end of the sampling tank 1 is fixedly sleeved with a connecting pipe 3;
[0032] An adjusting mechanism 4, the adjusting mechanism 4 is arranged on the outer surface of the sampling tank 1;
[0033] A locking mechanism 5, which is arranged in front of the sampling tank 1;
[0034] Among them, the adjustment mechanism 4 includes a first clamp 401, which is movably sleeved on the left side of the outer surface of the sampling tank 1, and the top of the first clamp 401 is movably sleeved with a first handle 402, the bottom end of the first handle 402 is movably connected to the outer surface of the sampling tank 1, and the right end of the first handle 402 is fixedly installed with a connecting block 403, and the outer surface of the connecting block 403 is movably sleeved with a second handle 404, the left end of the second handle 404 is movably connected to the right end of the first handle 402, and the right end of the second handle 404 is movably sleeved with a second clamp 405, the inner surface of the second clamp 405 is movably sleeved with the outer surface of the sampling tank 1, and the tops of the first clamp 401 and the second clamp 405 are respectively threadedly sleeved with bolts 406, and the first handle 402 will drive the connecting block 403 to move.
[0035] When the bolt 406 at the top of the first hoop 401 is rotated so that the bolt 406 releases the fixation of the first hoop 401, the first hoop 401 is pushed, which will cause the first hoop 401 to move to the left along the outer surface of the sampling tank 1. At this time, the first handle 402 movably connected to the first hoop 401 will move with the connecting block 403. When the pushing of the first hoop 401 is stopped, the bolt 406 at the top of the first hoop 401 is rotated again, which will re-fix the first hoop 401, thereby realizing the adjustment of the distance between the first handle 402 and the second handle 404, thereby facilitating the use of different operators.
[0036] Wherein, the locking mechanism 5 includes:
[0037] A circular hole 501 is provided on the left side of the top of the second handle 404 and is located above the connecting block 403. A round head clamping block 502 is movably sleeved inside the circular hole 501. The bottom end of the round head clamping block 502 passes through the connecting block 403 and extends to the inside of the connecting block 403 and is fixedly installed with a circular plate 503. The circular plate 503 is movably sleeved on the top of the inside of the connecting block 403.
[0038] Spring 504 , the spring 504 is fixedly mounted on the bottom end of the circular plate 503 , and the other end of the spring 504 is fixedly connected to the bottom end inside the connecting block 403 .
[0039] When the connecting block 403 moves, the inner wall of the circular hole 501 will squeeze the round head block 502, so that the round head block 502 moves downward with the circular plate 503 and compresses the spring 504. Under the restoring action of the spring 504, when the round head block 502 is realigned with the circular hole 501, the round head block 502 will be reset and embedded in the circular hole 501.

[0042] A threaded pipe 8 is fixedly mounted on the left end of the valve 6 , and a joint 9 is threadedly sleeved on the outer surface of the threaded pipe 8 .
[0043] Due to the existence of the joint 9, the connection between the sampling tube and the sampler is achieved.
[0044] Among them, a fixing plate 10 is fixedly installed on the front side of the top of the hydraulic display 7, and fixing rods 11 are fixedly installed on the left and right sides of the bottom of the front end of the fixing plate 10 respectively. A long plate 12 is movably sleeved on the outer surface of the fixing rod 11. The number of the fixing rods 11 and the long plate 12 are both two and they are symmetrical with each other about the center of the fixing plate 10.
[0045] The fixing plate 10 has a supporting and fixing function, and the long plate 12 will rotate around the fixing rod 11 as the axis when being pushed.
[0046] Among them, short rods 13 are fixedly installed on the top of the front end of the two long plates 12, and there are two short rods 13 with the same shape and size. Cover plates 14 are fixedly installed on the bottom ends of the two long plates 12, and there are two cover plates 14. The two cover plates 14 are movably connected to each other, and the rear ends of the two cover plates 14 are movably connected to the front end of the hydraulic display 7.
[0047] Due to the existence of the cover plate 14, dust protection for the screen of the hydraulic display 7 is achieved.
[0048] Among them, round shafts 15 are fixedly installed on the left and right sides of the top of the front end of the fixed plate 10, and the front end of the outer surface of the round shaft 15 is movably sleeved with a rotating rod 16. There are two rotating rods 16. The inner surfaces of the bottom ends of the two rotating rods 16 are movably sleeved with the outer surfaces of the two short rods 13 respectively, and the inner surfaces of the top ends of the two rotating rods 16 are movably sleeved with long rods 17 respectively. There are two long rods 17 and they are symmetrical with each other about the center of the fixed plate 10. The long rods 17 will cause the rotating rods 16 to rotate.
[0049] When the long rod 17 moves, a thrust is generated on the inner surface of the top end of the rotating rod 16, pushing the rotating rod 16 to rotate around the circular shaft 15 as the axis.
[0050] Among them, a fixing frame 18 is fixedly installed on the front side of the left and right ends of the fixing plate 10, and a double-threaded rod 19 is movably sleeved inside the fixing frame 18. Long handles 20 are fixedly sleeved on the left and right ends of the double-threaded rod 19 respectively. The outer surface of the long handle 20 is movably connected to the outer surface of the fixing frame 18. The left and right sides of the outer surface of the double-threaded rod 19 are respectively threadedly sleeved with movable blocks 21. There are two movable blocks 21, and the top ends of the two movable blocks 21 are respectively fixedly connected to the bottom ends of the two long rods 17.
[0051] When the double-threaded rod 19 rotates, the two movable blocks 21 will respectively carry the two long rods 17 to move in opposite directions along the inner surface of the fixed frame 18.
[0052] The working principle and use process of this utility model:
[0053] First, the operator rotates the bolt 406 at the top of the first hoop 401, so that the bolt 406 releases the fixation of the first hoop 401, and then the operator pushes the first hoop 401 to the left, so that the first hoop 401 moves to the left with the connecting block 403 through the first handle 402. At this time, as the connecting block 403 moves, the inner wall of the circular hole 501 will squeeze the outer surface of the round head block 502, so that the round head block 502 moves downward with the circular plate 503 and compresses the spring 504. When the distance between the first hoop 401 and the second hoop 405 is adapted to the size of the operator's palm, under the restoring action of the spring 504, the round head block 502 will be re-embedded in the circular hole 501, thereby locking the position of the connecting block 403. Then the operator rotates the bolt 406 at the top of the first hoop 401 again to re-fix the first hoop 401, so as to adjust the handle length, thereby facilitating the use of different operators.
[0054] Then the operator turns the long handle 20 to rotate the double-threaded rod 19. At this time, the two movable blocks 21 threadedly connected with the double-threaded rod 19 will respectively carry the two long rods 17 to move in opposite directions along the inner surface of the fixed frame 18. Since the inner surfaces of the top and bottom ends of the rotating rod 16 are respectively movably connected with the outer surfaces of the long rod 17 and the short rod 13, the two rotating rods 16 will rotate in opposite directions with the circular shaft 15 as the axis as the long rod 17 moves, so that the two rotating rods 16 respectively generate a thrust on the two short rods 13, pushing the two short rods 13 to respectively carry the two long plates 12 and the cover plate 14 to rotate in opposite directions with the fixed rod 11 as the axis, thereby releasing the dust protection of the hydraulic display 7 screen by the cover plate 14. Then the operator can connect the sampler and the sampling tube through the joint 9 to perform the liquefied natural gas sampling operation. The mutual cooperation of various mechanisms realizes the dust protection of the hydraulic display 7 screen, thereby preventing the hydraulic display 7 screen from being blurred due to dust adhesion.
