[0002] In industries such as petroleum and chemicals, large storage tanks are crucial facilities for storing various liquid raw materials and products. Double-dish floating roof structures are widely used in large storage tanks because they effectively reduce evaporation losses and safety risks. However, existing double-dish floating roof structures for large storage tanks still have many problems in practical use. Traditional double-dish floating roofs are usually assembled using complex bolted or welded connections, making installation and disassembly very cumbersome.

[0003] A search revealed Chinese Patent Publication No. CN221987141U, which discloses a double-disc floating roof structure for large storage tanks, relating to the field of storage tank technology. The structure includes a floating roof body composed of four sets of assembled modules, with fixing mechanisms evenly spaced at the top and bottom of each module. This invention employs the aforementioned structure, resulting in a buoyancy component with a low density, reducing the weight of the buoyancy unit and the load on the floating roof structure, thus improving the stability and safety of the floating roof. It also possesses excellent thermal insulation properties, effectively reducing the impact of heat on the buoyancy unit and minimizing the effect of temperature changes on the floating roof, thereby maintaining a stable internal temperature for the storage tank. Furthermore, all components are inorganic materials, exhibiting excellent corrosion resistance, resisting chemical corrosion, and extending the service life of the buoyancy unit. The honeycomb ceramic, diatomaceous earth, expanded vermiculite, and aerogel are natural or inorganic materials, making them environmentally friendly and free from harmful substances, thus meeting environmental protection requirements.

[0004] Although the device has been improved to some extent, it still requires staff to lock or unlock multiple fixed components one by one during installation or subsequent disassembly, which is cumbersome and time-consuming.

[0005] To address these issues, a double-dish floating roof structure for large storage tanks is proposed. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a large storage tank double-dish floating roof structure, including a floating roof module 1. The floating roof module 1 is assembled from three sets of floating roof 11 and one set of floating roof 2 12. Both floating roof 11 and floating roof 2 12 are fan-shaped. The outer walls of floating roof 11 and floating roof 2 12 are fixedly connected with sealing gaskets 1 2. The four sets of sealing gaskets 1 2 together form a ring, which contacts the inner wall of the storage tank to maintain a seal. The interior of floating roof 11 and floating roof 2 12 is provided with an installation mechanism. The installation mechanism facilitates the installation of the three sets of floating roof 11 and one set of floating roof 2 12 together. The installation mechanism includes an assembly component and a positioning component.

[0036] Reference Figure 2 - Figure 4 The assembly includes a movable block 51, which is slidably connected to the inner wall of the floating roof 11. The movable block 51 slides laterally. The inner wall on the right side of the movable block 51 is elastically connected to a locking block 53 by a compression spring 52. A locking groove 501 is provided on the right surface of the floating roof 11, and the locking groove 501 and the locking block 53 fit together.

[0037] Reference Figure 2 - Figure 4The floating roof module 1 is disc-shaped. A sealing gasket 2 3 is installed between three sets of floating roof units 11 and one set of floating roof units 12. The sealing gasket 2 3 is cross-shaped. The three sets of floating roof units 11 are located on the right rear, right front, and left front sides of the sealing gasket 2 3, respectively. The floating roof unit 12 is located on the left rear side of the sealing gasket 2 3. The top of the side surface of floating roof units 11 away from their upper locking block 53 is recessed, while the top of the side surfaces of floating roof units 11 and 12 near their upper locking blocks 53 are protruding. The protrusions and recesses fit together and can interlock. However, the entire side surface of floating roof unit 12 away from its upper locking block 53 is recessed to ensure no movement interference during assembly. Additionally, the side of the sealing gasket 2 3 that contacts floating roof unit 2 12 is thicker, preventing... A gap is created, and the locking block 53 passes through and slides on the left surface of the moving block 51. When the locking block 53 retracts into the moving block 51, it will compress the spring 52 to generate a reaction force. The locking block 53 is inserted into the inner wall of the slot 501, which can form a limit. When the locking blocks 53 on the adjacent floating roof 11 and floating roof 2 12 are inserted into the inner wall of the slot 501, the lower surface of the protrusion on it will fit with the upper surface of the recess on the other floating roof 11. The left end of the lower surface of the locking block 53 is set as a slope. When the slope is compressed, the locking block 53 will retract into the moving block 51 to release the obstruction. During assembly, since the locking block 53 is installed from top to bottom, the slope will be compressed. Therefore, during installation, there is no need to release the limit and can be assembled directly.

[0038] Reference Figure 3 - Figure 5 The positioning component includes a motor 41, which is existing technology and can be implemented by those skilled in the art. In this technical solution, the motor 41 has an IP67 waterproof rating, which can prevent rainwater from damaging it. The motor 41 is installed on the upper surface of the floating roof 11. The output shaft of the motor 41 is fixedly connected to a screw 42. After the motor 41 is started, it can drive the screw 42 to rotate forward or reverse. A sliding plate 43 is slidably connected to the inner wall of the floating roof 11. A connecting plate 44 is fixedly connected to the lower surface of the sliding plate 43. A slider 45 is fixedly connected to the bottom end of the rear surface of the connecting plate 44. A groove 401 is opened on the front surface of the moving block 51. The slider 45 and the groove 401 fit together.

[0039] Reference Figure 3 - Figure 5 The screw 42 passes through and is rotatably connected to the upper surface of the floating roof 11. The screw 42 also passes through and is threadedly connected to the inner surface of the slide plate 43. When the screw 42 rotates, it will drive the slide plate 43 to move longitudinally. The slider 45 is slidably connected to the inner wall of the slide groove 401. The connecting plate 44 is slidably connected to the inner wall of the floating roof 11. The slide groove 401 is inclined with the left side lower than the right side. When the slider 45 moves upward, it will squeeze the inner wall of the slide groove 401, thereby driving the moving block 51 and the locking block 53 to retract into the floating roof 11.

[0040] Working principle: When in use, first assemble the three sets of floating roof 11 from top to bottom, and finally assemble the floating roof 22 located on the left rear side of the sealing gasket 23 from top to bottom. During the assembly process, the inclined surface of the locking block 53 will be squeezed by the adjacent floating roof 11 or floating roof 22. The locking block 53 will retract into the moving block 51 to release the obstruction. When the floating roof 11 and floating roof 22 are aligned, the locking block 53 will be aligned with the slot 501. The compression spring 52 will push the locking block 53 out and engage with the slot 501 for limiting the position, realizing the rapid assembly of the device without the need to operate any fixing device.

[0041] When disassembly is required, the motor 41 is started to drive the screw 42 to rotate, which in turn causes the slide plate 43, connecting plate 44 and slider 45 to move upward. The upward-moving slider 45 will squeeze the slide groove 401, which in turn causes the moving block 51, compression spring 52 and locking block 53 to retract into the floating top 11 or floating top 2 12 to release the limit. At this time, the floating top 11 and floating top 2 12 can be directly separated. During operation, there is no need to manually unlock them one by one.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
