Description

Technical Field

[0001] This invention relates to the field of natural gas storage tank support technology, and more particularly to a support structure for a liquefied natural gas storage tank. Background Technology

[0002] Liquefied natural gas (LNG) is an energy form that is produced by cooling natural gas to a liquid state, which significantly reduces its volume and facilitates storage and transportation. When in use, LNG is generally stored in LNG storage tanks, which require support.

[0003] For example, the support structure for a liquefied natural gas (LNG) storage tank disclosed in patent CN220169178U can support the LNG storage tank, but it does not have the function of adjusting the clamping size according to the temperature of the LNG storage tank. As a result, it cannot support the LNG storage tank well when it expands and contracts with temperature, which reduces the effectiveness of use. Therefore, there is an urgent need to design a support structure for LNG storage tanks. Summary of the Invention

The insulated box is fixedly installed on the top of the support plate, and the insulated box is located at the center of the support plate; Temperature control component, which is located inside the insulation box, is used to control the stationary components.

[0006] As a further technical solution of the present invention, the fixing component includes: four L-shaped clamps, which are slidably disposed on the top of the support plate and are evenly distributed in a ring. The L-shaped clamps are made of heat-conducting material, and the top of the support plate is provided with a through-hole horizontal groove that is evenly distributed in a ring.

[0007] As a further technical solution of the present invention, a turntable is rotatably installed at the bottom center of the support disk, and a rotating shaft is vertically fixedly installed at the top center of the turntable.

[0008] As a further technical solution of the present invention, four slide rails evenly distributed in a ring are also horizontally fixed at the bottom of the support plate. Each slide rail has a vertically set slide plate slidably installed on its top, and the top of the slide plate passes through the corresponding horizontal groove and is fixedly installed on the bottom of the vertical side of the corresponding L-shaped clamp.

[0009] As a further technical solution of the present invention, four movable rods evenly distributed in a ring are rotatably installed on the outer edge of the top of the turntable, and the other four ends of the four movable rods are respectively rotatably installed on the inner side of the four slide plates.

[0010] As a further technical solution of the present invention, the temperature control component includes: a heat insulation plate, which is slidably disposed inside the heat preservation box; spring rods are vertically installed at the four corners of the bottom of the heat preservation box, and the tops of the four spring rods are fixedly installed at the bottom of the heat insulation plate; heat conduction plates are horizontally fixedly installed on the vertical sides of the four L-shaped clamps; the four heat conduction plates pass through the four sides of the heat preservation box respectively, and the heat conduction plates are slidably disposed inside the heat preservation box.

[0011] As a further technical solution of the present invention, a second bevel gear is rotatably installed inside the support disk. The second bevel gear meshes with the first bevel gear, and a rotating rod is horizontally fixedly installed at the center of the side of the second bevel gear. A limiting plate is rotatably sleeved on the surface of the rotating rod, and the end of the limiting plate is fixedly installed on the top of the turntable.

[0012] As a further technical solution of the present invention, a sleeve is slidably connected to the surface of the rotating rod via a spline, and the top ends of both the rotating rod and the sleeve pass through the support plate, with a knob fixedly installed at the top end of the rotating rod.

[0013] As a further technical solution of the present invention, a pull plate is fixedly sleeved on the top surface of the sleeve, a straight spring is sleeved on the surface of the rotating rod, and the two ends of the straight spring respectively rotate and abut against the opposite surfaces of the pull plate and the knob. A telescopic rod is vertically installed on the top side of the support plate. The fixed end and the telescopic end of the telescopic rod are slidably connected by a spline, and a stop block is fixedly installed on the telescopic end of the telescopic rod.

The top of the rack passes through the top of the support plate and the bottom of the insulation box and is then fixedly installed on the bottom of the heat insulation plate.

[0015] The beneficial effects of this invention are as follows: Firstly, this invention, through the setting of fixing components and temperature control components, can stably support liquefied natural gas storage tanks, and can also adapt to the temperature of liquefied natural gas storage tanks and annular mounting bases, avoiding the situation where the liquefied natural gas storage tanks and annular mounting bases cannot be stably fixed when they expand and contract with heat, thereby improving the performance of the equipment. Secondly, by setting up a fixing component and a temperature control component, the first gear and rack can be separated when the L-shaped clamp is manually adjusted, and then engaged again when the adjustment is adaptive, thus ensuring the stable operation of the device in both working states and improving the device's performance.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see the appendix Figure 1 -Appendix Figure 8 A support structure for a liquefied natural gas storage tank includes a tank body 1, an annular mounting base 2 fixedly installed at the bottom of the tank body 1, and further includes a support plate 3, a fixing component, an insulation box 4, and a temperature control component. The support plate 3 is located below the annular mounting base 2, and the support plate 3 is hollow inside. The support plate 3 is used to support the tank body 1 and the annular mounting base 2. The fixing component is located on the support plate 3 and is used to abut and fix the annular mounting base 2. The insulation box 4 is fixedly installed on the top of the support plate 3 and is located at the center of the support plate 3. The temperature control component is located inside the insulation box 4 and is used to control the fixing component. The above-mentioned structure can provide stable support for liquefied natural gas storage tanks and can also be adjusted according to the temperature of the liquefied natural gas storage tank and the annular mounting base 2.

[0021] Please see the appendix Figure 1 -Appendix Figure 8 In a preferred embodiment, the fixing component includes: four L-shaped clamps 5, which are slidably disposed on the top of the support plate 3 and are evenly distributed in a ring. The L-shaped clamps 5 are made of heat-conducting material. A through-hole and evenly distributed ring-shaped transverse groove 19 is opened on the top of the support plate 3. A turntable 14 is rotatably installed at the bottom center of the support plate 3. A rotating shaft 18 is vertically fixed at the top center of the turntable 14 and the top of the rotating shaft 18 is rotatably installed on the top of the support plate 3. A first bevel gear 22 is fixedly sleeved on the surface of the rotating shaft 18. Four evenly distributed ring-shaped slide rails 15 are also horizontally fixed at the bottom of the support plate 3. A vertically arranged slide plate 17 is slidably installed on the top of each slide rail 15. The top of the slide plate 17 passes through the corresponding transverse groove 19 and is fixedly installed on the bottom of the vertical side of the corresponding L-shaped clamp 5. Four evenly distributed ring-shaped movable rods 21 are rotatably installed on the outer edge of the top of the turntable 14 and the other four ends of the four movable rods 21 are rotatably installed on the inner side of the four slide plates 17. Furthermore, the movement of the sliding plate 17 causes the L-shaped clamping plate 5 to move away from the center of the support plate 3, thereby enabling the four L-shaped clamping plates 5 to fix the annular mounting base 2 at the bottom of the liquefied natural gas storage tank.

[0022] Please see the appendix Figure 1 -Appendix Figure 8 In a preferred embodiment, the temperature control assembly includes: a heat insulation plate 12, which is slidably disposed inside the insulation box 4; spring rods 13 are vertically installed at the four corners of the bottom of the insulation box 4, and the tops of the four spring rods 13 are fixedly installed at the bottom of the heat insulation plate 12; heat-conducting plates 6 are horizontally fixedly installed on the vertical sides of four L-shaped clamps 5, and the four heat-conducting plates 6 pass through the four sides of the insulation box 4 respectively, and are slidably disposed inside the insulation box 4; a second bevel gear 23 is rotatably installed inside the support plate 3, the second bevel gear 23 meshes with the first bevel gear 22, and a rotating rod 11 is horizontally fixedly installed at the center of the side of the second bevel gear 23; a limiting plate 26 is rotatably sleeved on the surface of the rotating rod 11, and the end of the limiting plate 26 is fixedly installed on the top of the turntable 14. A sleeve 20 is slidably fitted onto the surface of rod 11 via a spline. The top ends of both rod 11 and sleeve 20 pass through support plate 3. A knob 7 is fixedly installed at the top end of rod 11. A pull plate 8 is fixedly fitted onto the top surface of sleeve 20. A straight spring 27 is fitted onto the surface of rod 11, and the two ends of the straight spring 27 rotate and abut against the opposite surfaces of pull plate 8 and knob 7, respectively. A telescopic rod 10 is vertically installed on the top side of support plate 3. The fixed end and telescopic end of telescopic rod 10 are slidably connected via a spline, and a stop block 9 is fixedly installed at the telescopic end of telescopic rod 10. A first gear 24 is fixedly fitted onto the surface of sleeve 20. A rack 25 meshes with the side of the first gear 24, and the rack 25 is vertically set. The top end of rack 25 passes through the top of support plate 3 and the bottom of insulation box 4 and is fixedly installed at the bottom of insulation plate 12. Preferably, the rack 25 moves up and down, driving the first gear 24 to rotate in both directions, so that the L-shaped clamping plate 5 moves closer to or further away from the center of the support plate 3, adaptively clamping the annular mounting seat 2, avoiding the situation where the annular mounting seat 2 cannot be stably clamped due to thermal expansion and contraction.

[0023] The working principle of the present invention is as follows: When it is necessary to support the liquefied natural gas storage tank, the annular mounting base 2 is first placed on the top of the support plate 3, and the L-shaped clamp 5 is located inside the annular mounting base 2. Next, the pull plate 8 is pulled to move the sleeve 20 and cause the straight spring 27 to generate elastic force. The movement of the sleeve 20 causes the first gear 24 to move and separate from the rack 25, thus realizing the separation of the spline groove on the sleeve 20 and the spline on the rotating rod 11. At this time, the sleeve 20 and the rotating rod 11 are rotatably connected. The further stop 9 will descend and be positioned between the pull plate 8 and the support plate 3 to limit the pull plate 8. Then, rotating knob 7 drives rotating rod 11 to rotate. Rotating rod 11 drives second bevel gear 23 to rotate. Rotating second bevel gear 23 drives first bevel gear 22 to rotate. Rotating first bevel gear 22 drives rotating shaft 18 to rotate. Rotating shaft 18 drives turntable 14 to rotate. Turntable 14 drives movable rod 21 to move. Movable rod 21 moves slide plate 17 to move. Slide plate 17 moves L-shaped clamping plate 5 to move away from the center of support plate 3. Thus, the four L-shaped clamping plates 5 can fix the annular mounting seat 2 at the bottom of the liquefied natural gas storage tank. It should be noted that the movement of L-shaped clamping plate 5 will drive heat conduction plate 6, and the end of heat conduction plate 6 is always inside the insulation box 4. Finally, after pulling the pull plate 8 upward, the elastic force generated by the straight spring 27 will cause the pull plate 8 to move closer to the support plate 3. The pull plate 8 will reset and drive the first gear 24 to move. Then the first gear 24 and the rack 25 will be in a meshing state, and the pull plate 8 will block the stop block 9. When the liquefied natural gas (LNG) storage tank is properly supported and in use, if the temperature of the LNG storage tank and the annular mounting base 2 rises, the heat can be conducted to the interior of the insulation box 4 through the L-shaped clamp 5 and the heat-conducting plate 6. It should be noted that the gas above the insulation plate 12 inside the insulation box 4 is a gas with a high coefficient of thermal expansion. The gas above the insulation plate 12 expands due to heat, pushing the insulation plate 12 to move. The movement of the insulation plate 12 causes the rack 25 to move downwards, which in turn causes the first gear 24 to rotate. The rotation of the first gear 24 causes the sleeve 20 to rotate, which in turn causes the rotating rod 11 to rotate. The rotation of the rotating rod 11 is transmitted through the first bevel gear 22 and the second bevel gear... Wheel 23 and shaft 18 drive turntable 14 to rotate. The rotation of turntable 14 drives L-shaped clamping plate 5 to move via movable rod 21 and sliding plate 17, so that L-shaped clamping plate 5 moves closer to the center of support plate 3. This ensures that L-shaped clamping plate 5 can adaptably clamp the annular mounting seat 2, avoiding the situation where the annular mounting seat 2 expands and cracks due to heat. Similarly, if the temperature of liquefied natural gas storage tank and annular mounting seat 2 decreases, rack 25 moves upward, and first gear 24 rotates in the opposite direction. Furthermore, L-shaped clamping plate 5 will move further away from the center of support plate 3, ensuring stable clamping of annular mounting seat 2 and avoiding the situation where annular mounting seat 2 cannot be fixed due to cold contraction. In summary, this system can provide stable support for liquefied natural gas storage tanks and can also be adjusted according to the temperature of the liquefied natural gas storage tank and the annular mounting base 2, thereby improving the effectiveness of the equipment.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
