Description

Technical Field

[0001] This utility model relates to the technical field of oil tank storage equipment, and in particular to an adjustable internal floating roof for oil tanks. Background Technology

[0002] Oil tanks are large containers used to store crude oil, refined oil products, and other types of petrochemicals. They are widely used in petrochemical, energy storage, and other fields. They are typically vertical cylindrical structures with a large storage capacity. During oil storage, oil is prone to evaporation, which not only wastes resources but may also pose safety hazards. Furthermore, oil is susceptible to oxidation upon contact with air, affecting its quality. An internal floating roof is a device placed inside an oil tank and floating on the oil surface. It can isolate the oil from the air, greatly reduce the evaporation loss of the oil, reduce the pollution of the environment by oil and gas, and at the same time slow down the oxidation and deterioration of the oil, ensuring the quality of the oil. Traditional internal floating roofs are generally fixed structures that float directly on the oil surface and are attached to the inner wall of the oil tank by an edge sealing device.

[0003] The existing adjustable internal floating roof for oil tanks has the following shortcomings: Traditional internal floating roof sealing structures are mostly fixed, which cannot adapt to the deformation of the inner wall of the oil tank caused by long-term use. When local depressions or bulges appear on the inner wall of the oil tank, gaps are easily formed between the sealing device and the tank wall, leading to oil and gas leakage, increasing safety risks and wasting resources. In actual use, during the raising and lowering process, the internal floating roof may jam due to residual impurities on the tank wall or local unevenness. Traditional internal floating roofs lack effective adjustment methods. Once jammed, it not only affects the efficiency of oil transportation, but forced operation can also damage the internal floating roof structure. Existing internal floating roof outriggers are mostly fastened by welding or bolts. Precise alignment and long-term operation are required during installation. In later maintenance or replacement of outriggers, the disassembly process is cumbersome, requiring the use of various professional tools, which consumes a lot of manpower and time costs and reduces maintenance efficiency. Utility Model Content

[0004] This utility model proposes an adjustable internal floating roof for oil tanks, which achieves adaptive sealing and chuck adjustment through a sealing adjustment component, and improves the convenience of installation and maintenance by combining a quick-release outrigger structure, effectively solving the problems of sealing failure, chuck and outrigger disassembly difficulties of existing internal floating roofs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable internal floating roof for oil tanks, comprising an internal floating roof body, a sealing adjustment component provided on the outer surface of the internal floating roof body, a plurality of quick-release legs fixedly connected to the bottom of the internal floating roof body, a plurality of guide sleeves fixedly connected in a ring array on the top of the internal floating roof body, a rotating slot provided at the center of the top of the guide sleeve, an annular connecting groove provided on the outer surface of the internal floating roof body, and a plurality of connecting holes provided in a ring array on the inner surface of the annular connecting groove.

[0006] The sealing adjustment assembly includes an annular airbag, which is disposed on the inner surface of an annular connecting groove. Several connecting sleeves are fixedly connected in an annular array to the inner side of the outer surface of the annular airbag. The connecting sleeves are slidably inserted into the inner surface of the connecting hole. An annular rubber pad is disposed on the outer side of the outer surface of the annular airbag. The bottom end of the annular rubber pad is fixedly connected to the lower surface of the inner floating plate body. Several T-shaped pull plates are fixedly connected in an annular array to the top end of the annular rubber pad. The outer surface of the T-shaped pull plates is slidably connected to the inner surface of the guide sleeve. A connecting rod is movably connected to the end of the T-shaped pull plate away from the annular rubber pad. A rotating locking plate is movably connected to the end of the connecting rod away from the T-shaped pull plate. The rotating locking plate is rotatably locked into the inner surface of the rotating locking groove.

[0007] Preferably, a vertical rod is fixedly connected to the top of the rotating plate, and a handle is fixedly connected to the top of the vertical rod.

[0008] Preferably, a piston slide plate is slidably connected to the inner surface of the connecting sleeve, a sealing ring is fixedly connected to the outer surface of the piston slide plate, a tightening spring is fixedly connected to the side of the sealing ring away from the annular airbag, and the end of the tightening spring away from the sealing ring is fixedly connected to the inner wall of the connecting sleeve.

[0009] Preferably, the quick-release outrigger includes a connecting column, which is fixedly connected to the lower surface of the inner floating plate body. The outer surface of the connecting column has an annular sliding surface, and the inner surface of the annular sliding surface is slidably connected to a rotating ring.

[0010] Preferably, the quick-release outrigger includes an outrigger body, a threaded post is fixedly connected to the top of the outrigger body, a threaded sleeve is fixedly connected to the outer surface of the rotating ring, and the outer surface of the threaded post is threadedly connected to the inner surface of the threaded sleeve.

[0011] Preferably, a square insert is fixedly connected to the top of the threaded post, and a square slot is provided at the bottom of the connecting post, with the square insert slidingly inserted into the inner surface of the square slot.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. In this utility model, rotating the handle drives the rotating plate to rotate, which in turn pulls the connecting rod, thereby causing the T-shaped pull plate to slide horizontally along the guide sleeve. This causes the annular rubber pad to contract and compress the annular airbag. At this time, the gas in the annular airbag enters the connecting sleeve, pushing the piston slide plate to slide and reducing the overall outer diameter of the inner floating disk. This effectively addresses the issue of the inner floating disk getting stuck. When the T-shaped pull plate is released, under the action of the tightening spring, the piston slide plate pushes the gas in the connecting sleeve back into the annular airbag. The annular airbag expands and pushes the annular rubber pad to tightly adhere to the inner wall of the oil tank, achieving an adaptive seal. This structure not only quickly solves the problem of the inner floating disk getting stuck, but also automatically adjusts the sealing state according to the shape of the inner wall of the oil tank. Compared with the traditional fixed sealing structure, it significantly improves the sealing performance and the stability of the inner floating disk.

[0013] 2. In this utility model, when installing the outrigger, the square insert at the top of the outrigger body is first inserted into the square slot at the bottom of the connecting column for initial positioning. Then, by sliding and rotating the rotating ring within the annular sliding mechanism, the threaded sleeve is rotated, causing it to screw onto the outer surface of the threaded column, thus achieving quick fixation of the outrigger. When disassembling, the outrigger can be separated by rotating the rotating ring in the opposite direction. This quick-release outrigger structure requires no complicated tools and is simple and quick to operate. Compared with traditional welding or bolt connection methods, it significantly shortens the outrigger installation and disassembly time, significantly improves the maintenance efficiency of the inner floating roof, reduces labor and time costs, and facilitates the daily inspection of the inner floating roof and the replacement of the outrigger.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: it includes an inner floating disk body 1, a sealing adjustment component 2 is provided on the outer surface of the inner floating disk body 1, a plurality of quick-release legs 3 are fixedly connected to the bottom of the inner floating disk body 1, a plurality of guide sleeves 11 are fixedly connected to the top of the inner floating disk body 1 in a ring array, a rotating slot 12 is provided at the center of the top of the guide sleeve 11, an annular connecting groove 13 is provided on the outer surface of the inner floating disk body 1, a plurality of connecting holes 14 are provided in a ring array on the inner surface of the annular connecting groove 13, the sealing adjustment component 2 includes an annular airbag 21, the annular airbag 21 is provided on the inner surface of the annular connecting groove 13, a plurality of connecting sleeves 22 are fixedly connected in a ring array on the inner side of the outer surface of the annular airbag 21, the connecting sleeves 22 are slidably inserted into the inner surface of the connecting holes 14, an annular rubber pad 23 is provided on the outer side of the outer surface of the annular airbag 21, and the bottom end of the annular rubber pad 23 is connected to the inner floating disk. The lower surface of the main body 1 is fixedly connected to several T-shaped pull plates 24 in a ring array at the top of the annular rubber pad 23. The outer surface of the T-shaped pull plates 24 is slidably connected to the inner surface of the guide sleeve 11. A connecting rod 25 is movably connected to the end of the T-shaped pull plates 24 away from the annular rubber pad 23. A rotating clamping plate 26 is movably connected to the end of several connecting rods 25 away from the T-shaped pull plates 24. The rotating clamping plate 26 is rotatably clamped to the inner surface of the rotating clamping groove 12. A vertical rod 27 is fixedly connected to the top of the rotating clamping plate 26. A handle 28 is fixedly connected to the top of the vertical rod 27. A piston slide plate 221 is slidably connected to the inner surface of the connecting sleeve 22. A sealing ring 222 is fixedly connected to the outer surface of the piston slide plate 221. A pressing spring 223 is fixedly connected to the side of the sealing ring 222 away from the annular airbag 21. The end of the pressing spring 223 away from the sealing ring 222 is fixedly connected to the inner wall of the connecting sleeve 22. The overall effect of Embodiment 1 is as follows: When the inner floating roof encounters jamming during its ascent and descent within the oil tank, the operator can hold and rotate the handle 28. The upright 27 drives the rotating clamping plate 26 to rotate within the rotating clamping groove 12. The rotating clamping plate 26 pulls the connecting rod 25, which in turn drives the T-shaped pull plate 24 to slide horizontally along the inner surface of the guide sleeve 11. This causes the annular rubber pad 23 to contract inward and compress the annular airbag 21. After the annular airbag 21 is compressed, the internal gas enters the connecting sleeve 22 through the communication channel between the connecting sleeve 22 and the annular airbag 21, pushing the piston slide plate 221 in the connecting sleeve. The inner float slides within the sleeve 22, reducing its overall outer diameter and allowing it to pass smoothly through the chuck position. Once the inner float has passed the chuck position, the handle 28 is released. Under the elastic force of the tension spring 223, the piston slide plate 221 pushes the gas inside the sleeve 22 back into the annular air bladder 21. The annular air bladder 21 expands and pushes the annular rubber pad 23 to tightly adhere to the inner wall of the oil tank. Because the annular rubber pad 23 has a certain elasticity, it can adaptively adjust according to the shape of the inner wall of the oil tank, filling the gaps in uneven areas of the inner wall, achieving efficient sealing, effectively reducing oil and gas leakage, and improving the safety and stability of oil storage.

[0019] Example 2: Figure 4 As shown, this utility model provides a technical solution: the quick-release support leg 3 includes a connecting post 31, which is fixedly connected to the lower surface of the inner floating plate body 1. The outer surface of the connecting post 31 is provided with an annular sliding 32, and the inner surface of the annular sliding 32 is slidably connected with a rotating ring 33. The quick-release support leg 3 includes a support leg body 36, the top of the support leg body 36 is fixedly connected with a threaded post 37, the outer surface of the rotating ring 33 is fixedly connected with a threaded sleeve 34, the outer surface of the threaded post 37 is threadedly connected to the inner surface of the threaded sleeve 34, the top of the threaded post 37 is fixedly connected with a square insert post 38, the bottom end of the connecting post 31 is provided with a square slot 35, and the square insert post 38 is slidably inserted into the inner surface of the square slot 35. The overall effect of embodiment 2 is as follows: When installing the quick-release outrigger 3, the square insert 38 on the top of the outrigger body 36 is aligned with the square slot 35 at the bottom of the connecting post 31 and inserted to achieve initial positioning of the outrigger body 36 and the connecting post 31, ensuring accurate installation of the outrigger. Subsequently, by rotating the rotating ring 33, due to the sliding connection between the rotating ring 33 and the connecting post 31 via an annular sliding 32, the rotating ring 33 can rotate smoothly on the connecting post 31, driving the threaded sleeve 34 fixed on the outer surface of the rotating ring 33 to rotate. The threaded sleeve 34 and the threaded post 37 are engaged by threads, and as the threads... The rotation of the threaded sleeve 34 gradually tightens it onto the outer surface of the threaded post 37, achieving a firm connection between the outrigger body 36 and the inner floating disc body 1. When disassembling the outrigger, the rotating ring 33 is rotated in the opposite direction to unscrew the threaded sleeve 34 from the threaded post 37. After the threaded sleeve 34 is completely detached from the threaded post 37, the square insert 38 is pulled out of the square slot 35, allowing for quick disassembly of the outrigger body 36. The entire process requires no complex tools, is simple and efficient, significantly shortens the installation and disassembly time of the inner floating disc outriggers, reduces the manpower and time costs of maintenance, and facilitates daily inspection and outrigger replacement of the inner floating disc.

[0020] The working principle of the entire equipment is as follows: During the oil storage process, the inner floating roof body 1 floats on the oil surface. As the oil enters and exits the oil tank, the inner floating roof body 1 rises and falls accordingly. When the inner floating roof body 1 encounters a jamming problem during the rising and falling process, the operator activates the adjustment function of the sealing adjustment component 2 by turning the handle 28. The handle 28 drives the upright 27 and the rotating clamping plate 26 to rotate, pulling the connecting rod 25, causing the T-shaped pull plate 24 to drive the annular rubber pad 23 to contract, squeezing the annular air bladder 21. The gas pushes the piston slide plate 221, reducing the overall outer diameter of the inner floating roof, helping the inner floating roof to pass smoothly through the jamming position. After passing through the jamming position, the handle 28 is released, the spring 223 is tightened, and the piston slide plate 221 is pushed, allowing the gas to flow back to the annular air bladder 21. The annular air bladder 21 expands and pushes the annular rubber pad 23 to tightly fit the inner wall of the oil tank, achieving self-adaptive sealing. When installing or removing the support legs at the bottom of the inner floating roof body 1, the structural characteristics of the quick-release support legs 3 are utilized. During installation, the square insert 38 is first used to initially position the support legs by interlocking with the square slot 35. Then, the rotating ring 33 is rotated to tighten the threaded sleeve 34 onto the threaded post 37, thus quickly fixing the support legs. During disassembly, the rotating ring 33 is rotated in the opposite direction to unscrew the threaded sleeve 34 and pull out the square insert 38, allowing for quick disassembly of the support legs. The guide sleeve 11 and the rotating slot 12 provide guidance and limit for the movement of the T-shaped pull plate 24 and the rotating slot 26, ensuring the stable operation of the sealing adjustment assembly 2. The connecting sleeve 22, piston slide plate 221, sealing ring 222, and top spring 223 work together to achieve controllable flow and pressure regulation of the gas in the annular airbag 21, further ensuring the reliability of the sealing adjustment function. Through the coordinated work of the sealing adjustment assembly 2 and the quick-release support legs 3, the safety, stability, and ease of maintenance of the inner floating roof during oil storage are effectively improved.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
