Description

Technical Field

[0001] The invention relates to the technical field of oil storage tanks, in particular to a liquid-immersed stainless steel inner floating plate with a beam structure and adjustable legs. Background Art

[0002] Floating roof oil storage tanks are also called floating roof tanks. They are an important category of oil storage tanks. They are different from ordinary fixed roof oil tanks without this device because they are designed with a "floating roof device" that can "float" on the oil surface and rise and fall with the oil level in the tank. Floating roof oil storage tanks are divided into two types: internal floating roof type and external floating roof type. Because the floating plate can be flexibly moved up and down to get close to the liquid surface, the gas space above the liquid surface can be greatly reduced, thus greatly reducing the evaporation loss of the stored materials.

[0003] A sealing ring is provided on the circumferential surface of a conventional floating plate to seal the gap between the floating plate and the inner wall of the oil tank to suppress the evaporation loss of the oil. Since the floating plate will float up and down with the liquid level of the oil, the sealing ring will constantly rub against the inner wall of the oil tank, causing the sealing ring to wear and affect the sealing effect, thereby aggravating the evaporation loss of the oil, which can be further improved.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 2 The immersion type stainless steel beam structure with adjustable legs and inner floating plate includes an upper floating plate 100 and a lower floating plate 200. Telescopic legs 300 are fixed in array between the upper floating plate 100 and the lower floating plate 200. A telescopic driving assembly 400 is fixedly installed at the top center of the lower floating plate 200. The telescopic driving assembly 400 drives the telescopic legs 300 to extend and retract, thereby adjusting the distance between the upper floating plate 100 and the lower floating plate 200. A sealing ring 500 is fixedly installed between the circumferential surfaces of the upper floating plate 100 and the lower floating plate 200. The upper floating plate 100, the lower floating plate 200 and the sealing ring 500 enclose a circular cavity to ensure buoyancy. The upper floating plate 100 and the lower floating plate 200 are both provided with sealing sleeves 600 in an array, and the sealing sleeves 600 are internally plugged with guide rods 700, and the two ends of the guide rods 700 are respectively fixedly mounted on the top wall and the bottom wall of the oil storage tank, and the upper floating plate 100 and the lower floating plate 200 are slidably connected to the guide rods 700 through the sealing sleeves 600. The number of guide rods 700 is at least three groups. In this embodiment, the number of guide rods 700 is three groups. The upper floating plate 100 and the lower floating plate 200 are limited by the guide rods 700, so that the upper floating plate 100 and the lower floating plate 200 can only move in the vertical direction, and the upper floating plate 100 and the lower floating plate 200 are inhibited from rotating.

[0019] See also Figure 3 The upper floating plate 100 includes a carrier plate 101, a avoidance cover 102 is integrally formed at the center of the top of the carrier plate 101, a sealing ring 103 is fixedly installed on the top of the carrier plate 101, and the sealing ring 103 is sleeved on the outside of the avoidance cover 102, so as to form a first floating chamber between the carrier plate 101 and the sealing ring 103.

The hollow skeleton 104 includes an annular frame 1041, which is sleeved on the outside of the avoidance cover 102. The annular frame 1041 is fixed with a support arm 1042 in a circumferential array. The annular frame 1041 and the support arm 1042 are both hollow and connected to each other. While the hollow skeleton 104 ensures the structural strength, the upper floating plate 100 has a certain buoyancy.

[0020] See also Figure 4 The lower floating plate 200 includes a second carrier plate 201, a second annular frame 202 is fixedly installed at the center of the top of the second carrier plate 201, and a second support arm 203 is fixed on the circumferential surface array of the second annular frame 202. The second annular frame 202 and the second support arm 203 are both hollow and interconnected, and a sealing cover 204 is fixedly installed on the top of the second carrier plate 201. A second floating cavity is formed between the second carrier plate 201 and the sealing cover 204.

[0021] See also Figure 5-Figure 6Each telescopic leg 300 includes a support rod 301 fixedly mounted on the top of the lower floating plate 200, and a square sleeve 302 is sleeved on the top of the support rod 301. The support rod 301 and the square sleeve 302 can slide relative to each other to perform telescoping. An arc plate 303 is fixedly mounted on the side of the square sleeve 302 facing the center of the lower floating plate 200, and two sets of sliding columns 304 are fixedly mounted on the inner arc surface of the arc plate 303.

[0022] See also Figure 5-Figure 6 , a connection seat 305 is fixedly installed at the bottom of the support rod 301, a convex column 306 is fixedly installed at the top of the square sleeve 302, a through hole 206 is opened in an array on the surface of the sealing cover 204, a pad 205 is fixedly installed on the top of the support arm 203, the connection seat 305 passes through the through hole 206 and is fixedly installed on the top of the pad 205, and the connection seat 305 seals the through hole 206 at the same time. A through hole 105 is opened in an array at the bottom of the carrier 101, and the convex column 306 passes through the through hole 105 and is fixedly installed at the bottom of the hollow frame 104. Similarly, the convex column 306 seals the through hole 105. Thus, the support rod 301 and the square sleeve 302 are connected to the support arm 203 and the hollow frame 104 respectively to ensure the connection strength.

[0023] See also Figure 6-Figure 8 The telescopic drive assembly 400 includes an annular seat 401 fixedly mounted on the top of the sealing cover 204. An annular groove 402 is provided on the top of the annular seat 401. The cross section of the annular groove 402 is in the shape of a "convex" character. An annular flange 404 is slidably connected in the annular groove 402. A support ring 403 is fixedly mounted on the top of the annular flange 404. The support ring 403 passes through the opening of the annular groove 402. The cross section of the support ring 403 is in the shape of an inverted L. The support ring 403 is supported by the annular seat 401 so that the support ring 403 can be stably rotatably connected to the annular seat 401.

[0024] A rotating ring 405 is fixedly mounted on the outer wall of the top of the support ring 403. A guide groove 406 is arranged in an array on the circumference of the rotating ring 405. Each guide groove 406 is composed of two mutually parallel inclined grooves. The slide column 304 is slidably connected in the guide groove 406. In addition, the arc plate 303 is attached to the outer wall of the rotating ring 405. Therefore, when the rotating ring 405 rotates following the support ring 403, the rotating ring 405 located at the inner wall of the inclined groove will squeeze the slide column 304 and push the slide column 304, the arc plate 303 and the square sleeve 302 to rise or fall.

[0025] An inner gear ring 407 is fixedly mounted on the inner wall of the support ring 403, and four groups of motors 408 are fixedly mounted in an array on the top of the sealing cover 204. A gear 409 is fixedly mounted on the top output end of the motor 408, and the gear 409 is meshed with the inner gear ring 407. The gear 409 is driven to rotate by the motor 408, thereby driving the inner gear ring 407 and the support ring 403 to rotate.

[0026] See also Fig. 9 The sealing ring 500 includes two sets of fixing rings 501, which are fixedly mounted on the circumference of the upper floating plate 100 and the lower floating plate 200, respectively. The outer wall of the fixing ring 501 is provided with an annular embedding groove 502, and an embedding ring 503 is embedded in the annular embedding groove 502. The cross section of the embedding ring 503 is triangular. A rubber ring 504 is fixedly mounted between the two sets of embedding rings 503, and the rubber ring 504 has an annular cavity inside. Therefore, when the distance between the upper floating plate 100 and the lower floating plate 200 is reduced, the rubber ring 504 is driven to bend outward, increasing the extrusion force between the rubber ring 504 and the inner wall of the oil storage tank, thereby ensuring the sealing effect of the rubber ring 504.

[0027] A curved portion 5041 is provided in the middle of the inner side of the rubber ring 504. The cross section of the curved portion 5041 is arc-shaped and is bent toward the inside of the annular cavity. A vertical portion 5042 is provided in the middle of the outer side of the rubber ring 504. As the distance between the upper floating plate 100 and the lower floating plate 200 is reduced, the circular cavity space is reduced, so that the air pressure inside the circular cavity is increased, and pressure is applied to the curved portion 5041 to bend the curved portion 5041, so that the annular cavity space inside the rubber ring 504 is reduced, and the bending deformation of the rubber ring 504 is further promoted.

[0028] See also Fig.10 The sealing sleeve 600 includes a housing tube 601, which is fixed on the upper floating plate 100 or the lower floating plate 200. A rubber sleeve 602 is fixedly installed inside the housing tube 601. An annular cover 603 is inserted into both ends of the housing tube 601. The guide rod 700 passes through the rubber sleeve 602 and the annular cover 603. The rubber sleeve 602 and the annular cover 603 are tightly attached to the surface of the guide rod 700 to seal the gap between the housing tube 601 and the guide rod 700. The sealing sleeve 600 also includes a mounting seat 604 fixedly mounted on the top of the upper floating plate 100. The top of the mounting seat 604 is provided with a roller 605 in an array. The roller 605 is attached to the surface of the guide rod 700 and rolls. During the up and down movement of the upper floating plate 100 and the lower floating plate 200, the roller 605 rolls on the guide rod 700. The rollers 605 arranged in an array are attached to the guide rod 700 to limit the relative position between the lower floating plate 200 and the guide rod 700.

[0029] When in use, the motor 408 drives the gear 409 to rotate, driving the support ring 403 to rotate, thereby driving the swivel 405 to rotate. The swivel 405 is located at the inner wall of the guide groove 406 to squeeze the sliding column 304, and push the square sleeve 302 to move downward, so that the distance between the upper floating plate 100 and the lower floating plate 200 is reduced, so that the rubber ring 504 is bent outward; at the same time, the internal air pressure of the circular cavity between the upper floating plate 100 and the lower floating plate 200 increases, and the bending part 5041 bends into the annular cavity in the rubber ring 504 under the action of the air pressure, so that the internal annular cavity space of the rubber ring 504 is reduced, and the internal air pressure of the annular cavity is increased, which further ensures the extrusion force between the rubber ring 504 and the inner wall of the oil storage tank, and ensures the sealing effect.
