Description

Technical Field

[0001] This application relates to the field of LNG storage tank technology, and more specifically, to an automatic balancing gas lifting device for the top of an LNG storage tank using spring steel plates. Background Technology

[0002] LNG storage tanks, or liquefied natural gas storage tanks, are the most important equipment in receiving terminals, used to store large quantities of liquefied natural gas. Different LNG storage tanks have different safety factors, and their safety is affected by various factors such as internal pressure and the evaporation rate of liquefied natural gas.

[0003] Existing LNG storage tanks cannot achieve true automatic balancing during use, therefore, during the gas lifting process on the tank top, the stability and safety of the tank top cannot be guaranteed.

[0004] To address the aforementioned issues, this application provides an automatic balancing gas lifting device for the top of an LNG storage tank that utilizes spring steel plates. Utility Model Content

[0005] The technical solution provided in this application for an automatic balancing gas lifting device for the top of an LNG storage tank using spring steel plates is as follows:

[0006] An automatic balancing gas lifting device for the top of an LNG storage tank using spring steel plates includes a tank top, and an auxiliary mechanism is provided on the outside of the tank top;

[0007] The auxiliary mechanism includes a storage tank, which is fitted onto the outer side of the tank top. A pressure-bearing ring is installed on the top of the storage tank. Multiple support plates are fixedly connected to the top of the pressure-bearing ring. Four connecting brackets (first type) are fixedly connected to the inner side of the multiple support plates. Four connecting brackets (second type) are fixedly connected to the top of the tank top. Rotating rods (first type and second type) are respectively embedded in the four connecting brackets (first type and second type). Pullers are fixedly sleeved on the outer side of the multiple rotating rods (first type and second type). Four steel wire ropes are sleeved on the outer side of the multiple pulleys. Gears are fixedly sleeved on the outer side of the four rotating rods (first type). Toothed plates are meshed on one side of each of the four gears. Fixed plates are fixedly connected to one side of each of the four toothed plates. Springs are fixedly connected to the bottom of each of the four fixed plates. Control components are provided on the outer side of each of the four springs.

[0008] Furthermore, the four connecting frames one and four connecting frames two are evenly distributed around the centerline of the storage tank, and the four rotating rods one and four rotating rods two are connected to the four connecting frames one and four connecting frames two by bearings.

[0009] Furthermore, the control component includes four movable plates, each of which is fixedly connected to the bottom end of one of the four springs.

[0010] The above technical solution, by setting up a movable plate, facilitates the movement of the toothed plate in the later stages.

[0011] Furthermore, each of the four movable plates is fixedly connected to an electric push rod, and each of the four connecting frames is equipped with a monitor and a central processing unit on its outer side.

[0012] The above technical solution allows for real-time monitoring of the rotation angle of the rotating rod by setting up a monitor.

[0013] Furthermore, a monitor and a central processing unit are installed on the outer side of each of the four connecting frames. The monitor is electrically connected to the input terminal of the central processing unit, and the central processing unit is electrically connected to the input terminal of the electric push rod.

[0014] Furthermore, each of the four wire ropes is matched with a plurality of pulleys, and the outer sides of the four springs are coated with anti-corrosion paint.

[0015] With the above technical solution, since the outer sides of all four springs are coated with anti-corrosion paint, the four springs can have an anti-corrosion effect.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] During operation, when one side of the tank top rises, the corresponding spring will be unloaded and rebound. This rebound, pressing the fixing plate, causes the toothed plate to move. Because the toothed plate meshes with the gear, the gear rotates, which in turn drives the pulley to rotate, winding up the wire rope. Simultaneously, in conjunction with the control components, the opposite rotating rod rotates, adjusting the height of the opposite tank top by winding up the wire rope. This ensures that the symmetrical points of the tank top edges automatically adjust their balance during the air lifting process, maintaining a smooth ascent. Attached Figure Description

[0027] Example:

[0028] This application discloses an automatic balancing gas lifting device for the top of an LNG storage tank using spring steel plates. Please refer to [link to relevant documentation]. Figures 1 to 4 It includes a tank top 1, and an auxiliary mechanism is provided on the outside of the tank top 1;

[0029] The auxiliary mechanism includes a storage tank 2, which is fitted onto the outside of a tank top 1. A pressure-bearing ring 3 is installed on the top of the storage tank 2. Multiple support plates 4 are fixedly connected to the top of the pressure-bearing ring 3. Four connecting frames 1 5 are fixedly connected to the inner side of the multiple support plates 4. Four connecting frames 2 6 are fixedly connected to the top of the tank top 1. Rotating rods 1 7 and 2 8 are respectively embedded in the four connecting frames 1 5 and 2 6. Pulleys 9 are fixedly sleeved on the outer side of the multiple rotating rods 1 7 and 2 8. Four steel wire ropes 10 are sleeved on the outer side of the multiple pulling wheels 9. Gears 11 are fixedly sleeved on the outer side of the four rotating rods 1 7. Tooth plates 12 are meshed on one side of each of the four gears 11. Fixing plates 13 are fixedly connected to one side of each of the four tooth plates 12. Springs 14 are fixedly connected to the bottom of each of the four fixing plates 13. The four connecting frames 1 5 and 2 6 are evenly distributed around the centerline of the storage tank 2. The connections between the four rotating rods 1 7 and 2 8 and the four connecting frames 1 5 and 2 6 are movably connected by bearings.

[0030] Please see Figure 3 The four springs 14 are equipped with control components on their outer sides. The control components include four movable plates 15, which are fixedly connected to the bottom ends of the four springs 14 respectively. Each of the four movable plates 15 is fixedly connected to an electric push rod 16 between itself and the pressure ring 3. Each of the four connecting frames 6 is equipped with a monitor 17 and a central processing unit 18. By setting the movable plates 15, it is easy to drive the toothed plate 12 to move later. At the same time, by setting the monitor 17, the rotation angle of the rotating rod 7 can be monitored in real time.

[0031] Please see Figure 2 , Figure 3 and Figure 4 The monitor 17 is electrically connected to the input terminal of the central processing unit 18, and the central processing unit 18 is electrically connected to the input terminal of the electric push rod 16. The four steel wire ropes 10 are respectively matched with multiple pulleys 9. The outer side of the four springs 14 is coated with anti-corrosion paint. Because the outer side of the four springs 14 is coated with anti-corrosion paint, the four springs 14 can have an anti-corrosion effect.

[0032] The implementation principle of this embodiment is as follows: During use, when one side of the tank top 1 is raised during the air lifting process, the corresponding spring 14 will be unloaded and rebound. By squeezing the fixed plate 13, the toothed plate 12 moves. Since the toothed plate 12 meshes with the gear 11, the gear 11 can rotate. The rotating rod 7 drives the pulley 9 to rotate, completing the winding operation of the wire rope 10. At this time, the monitor 17 will detect the angle of rotation of the rotating rod 7 and transmit the signal to the central processor 18 located on the opposite side. Then, the central processor 18 transmits the signal to the electric push rod 16 located on the opposite side. The electric push rod 16 drives the fixed plate 13 to move, causing the rotating rod 7 located on the opposite side to rotate. By winding the wire rope 10, the height of the opposite tank top 1 is adjusted accordingly to ensure that the mutually symmetrical points of the edge of the tank top 1 can always automatically adjust the balance during the air lifting process and maintain a stable rise.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
