[0002] Gas tanks are steel containers for storing industrial and domestic gas. There are two types: wet gas tanks and dry gas tanks. Wet gas tanks are sleeve-type cylindrical structures sealed with water; dry gas tanks are piston-type structures sealed with thin (dry) oil or soft film.

[0003] The patent with publication number CN213236946U discloses a gas tank piston horizontal adjustment device. When the horizontal error of the piston body is too large, the sliding of the cross bar through the first slider and the first slide groove is blocked under the action of the vertical rod fixation, thereby requiring user intervention to facilitate user adjustment.

[0004] However, when the device is in use, a level gauge on the top is needed to determine whether the piston is level. If the piston is tilted, manual intervention is required to level the piston. The entire process is not automated enough and therefore needs further improvement. Utility Model Content

The two groups of adjustment mechanisms 1 are connected in a cross shape on the top of the gas tank. Each adjustment mechanism 1 includes a mounting assembly and a connecting assembly 7 fixed to the upper surface of the gas tank piston 16, the mounting assembly includes a vertical plate 3, and the top side wall of the vertical plate 3 is fixedly connected to a support plate 4, the bottom end of the vertical plate 3 is fixedly connected to a bottom plate 2, the support plate 4 is provided with a slide groove 41 on the side away from the vertical plate 3, a slide plate 5 is slidably connected inside the slide groove 41, a top shell 6 is fixed on the upper surface of the slide plate 5, and a winding and unwinding assembly and a wire pressing assembly are provided inside the top shell 6.

[0026] like Figure 2 As shown, a strip-shaped opening 42 is formed on the bottom wall of the support plate 4 , a sliding block 52 is fixed to the lower surface of one end of the sliding plate 5 located inside the sliding groove 41 , and the sliding block 52 is slidably connected to the strip-shaped opening 42 .

[0027] When the slide plate 5 moves along the slide groove 41 , the slider 52 moves in the strip-shaped opening 42 , and the slider 52 limits the movement of the slide plate 5 , thereby preventing the slide plate 5 from being separated from the slide groove 41 .

[0028] A locking bolt 43 penetrates through the top wall of the support plate 4 away from the vertical plate 3 and is threadedly connected thereto.

[0029] The positions of the top shell 6 and the reeling and unreeling assembly can be changed by adjusting the slide plate 5 to move in the slide groove 41 . The position of the top shell 6 and the reeling and unreeling assembly can be flexibly adjusted when installing the device. After the adjustment is completed, the locking bolt 43 can be tightened to fix the slide plate 5 .

[0030] A reinforcing plate 14 is fixedly connected between the upper surface of the supporting plate 4 and the vertical plate 3. The reinforcing plate 14 can increase the connection strength between the supporting plate 4 and the vertical plate 3.

[0031] like Figure 1-Figure 2 As shown, the connection assembly 7 includes a mounting plate 71 fixedly connected to the gas tank piston 16 , a tension sensor 72 is fixedly connected to the upper surface of the mounting plate 71 , and a pull wire 73 is fixedly connected to the force-bearing end at the top of the tension sensor 72 .

[0032] The gas tank piston 16 can be pulled up and down by the pull wire 73 , so as to level the gas tank piston 16 , and the tension sensor 72 can detect the tension on the pull wire 73 in real time.

[0033] like Figure 1-Figure 3 As shown, the reel assembly includes a motor 8 fixed inside the top shell 6, the driving end of the motor 8 is fixedly connected to the wire wheel 9, the end of the slide plate 5 located directly below the wire wheel 9 is provided with a through hole 51, the top end of the pull wire 73 passes through the through hole 51 and is wound around the surface of the wire wheel 9, and the motor 8 and the tension sensor 72 are both electrically connected to the main controller 15.

[0034] The motor 8 drives the wire wheel 9 to rotate forward or reversely to realize the winding or unwinding of the pull wire 73, thereby realizing the adjustment of the gas tank piston 16.

[0037] Working principle: the adjusting mechanism 1 is fixedly mounted on the top of the gas tank through the bottom plate 2, and then the mounting plate 71 is fixed on the upper surface of the gas tank piston 16, and then the sliding plate 5 is moved to ensure that the wire 73 is completely vertical. After the adjustment is completed, the locking bolt 43 is tightened, and two sets of adjusting mechanisms 1 are installed in this way. When the device is working, no matter whether the gas tank piston 16 moves upward or downward, the tension sensors 72 of all adjusting mechanisms 1 will monitor the tension on the corresponding wire 73 in real time, and transmit the tension value to the main controller 15, and the main controller 15 will judge the tension values ​​of the four tension sensors 72. If the four tension values ​​are different, it means that the gas tank piston 16 is tilted. At this time, the main controller 15 controls the motors 8 of the four adjusting mechanisms 1 to reel or unreel the wire 73 until the tension on the wire 73 of the four adjusting mechanisms 1 is exactly the same and the same as the set tension value. At this time, the gas tank piston 16 is in a horizontal state. The device can realize the leveling of the gas tank piston 16 without manual intervention, which is more worry-free and convenient to use.
