Description

Technical Field

[0001] The utility model relates to a fireproof floating roof oil tank rubber sealing belt structure, belonging to the technical field of floating roof oil tanks. Background Art

[0002] A floating roof tank is a tank whose roof floats on the oil surface. Deformation of the float plate can occur during long-term, frequent operation. This is affected by factors such as oil corrosion, temperature fluctuations, climate change, tank foundation settlement, tank deformation, the installation of the float plate's top slide, and the integrity of the float plate's accessories. This can cause the float plate's geometry and dimensions to change, gradually deforming, and developing an uneven surface. This deformation can cause the float plate to tilt during operation due to varying buoyancy forces at various locations, leading to the oil metering guide tube becoming stuck and oil leaking through the seal and automatic breather valve holes onto the float plate, causing it to sink.

[0003] A Chinese patent (publication number: CN 216637560 U) discloses a rubber sealing strip for floating roof oil tanks with a fire prevention assembly. The strip comprises a strip body, a bottom ring, a pin mechanism, a side ring, and a liquid reservoir. The bottom ring is connected to the lower sidewall of the strip body, within which is mounted a self-retracting pin mechanism. A side ring is mounted on the outer side of the strip body at the upper end of the bottom ring, and within the lower side of the side ring is a liquid reservoir for rapidly releasing cooling liquid. The pin mechanism and liquid reservoir operate autonomously under high temperature and pressure, achieving highly effective cooling and fire extinguishing, enhancing the performance of the sealing strip.

[0004] The above patent lacks a device for replacing the belt body. In actual use, the belt body is easily deformed or damaged, or when a fire occurs in the tank, the belt body will also be damaged. Since the belt body in the above patent cannot be replaced, it is basically a disposable device with a high investment cost. In addition, it lacks a device that can remind and alarm the outside world, which makes it inconvenient for people to quickly deal with the fire.

[0005] Therefore, a fireproof floating roof oil tank rubber sealing belt structure is proposed. Utility Model Content

Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a fireproof floating roof oil tank rubber sealing belt structure, including a bottom ring 1, a belt body 2 is provided on the top of the bottom ring 1, a disassembly mechanism 3 is provided on the inner side of the bottom ring 1, and the bottom ring 1 and the belt body 2 are detachably connected through the disassembly mechanism 3, the number of the disassembly mechanism 3 is four groups, the disassembly mechanism 3 includes an inner groove 301, the number of the inner groove 301 is two, both are opened on the inner surface of the inner side of the bottom ring 1, one end of the inner side of the inner groove 301 is fixedly connected to a spring 302, the inner side of the spring 302 is fixedly connected to a moving block 303, and the moving block 303 is slidably connected to the inner side of the inner groove 301, the inner side of the moving block 303 is fixedly connected to an insert block 304, and the end of the moving block 303 close to the inner side of the bottom ring 1 is fixedly connected to a toggle rod 305.

[0030] By providing the disassembly mechanism 3, when the belt body 2 needs to be replaced, the toggle rod 305 is simultaneously pulled outward, so that the toggle rod 305 drives the moving block 303 to move, and the moving block 303 drives the inserting block 304 to move and squeezes the spring 302, causing the spring 302 to deform. After the inserting block 304 is disengaged from the inner side of the insertion hole 8, the belt body 2 is pulled upward, so that the belt body 2 drives the inserting rod 7 to disengage from the inner side of the slot 6, and the belt body 2 can be replaced. This prevents the inconvenience of replacing the belt body 2 when the belt body 2 is damaged, thereby reducing investment costs.

[0031] Example 2

[0032] like Figure 2 and Figure 5As shown, in one embodiment, an alarm device 4 is provided on the outside of the bottom ring 1, and the alarm device 4 includes a temperature sensor 401 and a temperature alarm 402. The temperature sensor 401 is fixedly connected to the left side of the outside of the bottom ring 1, and the temperature alarm 402 is fixedly connected to the right side of the outside of the bottom ring 1. Outward-expanding speakers 403 are provided on the front and rear sides of the top of the temperature alarm 402, and a warning light 404 is provided on the top of the temperature alarm 402 and on the inner side of the outward-expanding speaker 403. There are two groups of warning lights 404, and the temperature alarm 402, the outward-expanding speaker 403 and the warning light 404 are electrically connected to the temperature sensor 401.

[0033] By means of the alarm device 4, by setting up a temperature sensor 401, a temperature alarm 402, an external speaker 403 and a warning light 404, the temperature inside the tank can be monitored in time, and when the temperature is too high, it can serve as a warning in time, sounding an alarm and a warning light, so that people can quickly discover the fire and take fire-fighting measures in time.

[0034] When the utility model is working: first, when a fire occurs in the tank, the high temperature of the combustion causes the airbag 5 to melt and tear, leaking the foam fire extinguishing agent inside it, and taking preliminary fire extinguishing measures in the tank. In addition, by setting the temperature sensor 401, the temperature alarm 402, the external speaker 403 and the warning light 404, the temperature in the tank can be monitored in time, and when the temperature is too high, it can play a warning role in time, and emit an alarm and a warning light, so that people can quickly discover the fire, and thus take fire extinguishing measures in time. After the fire is extinguished, If the belt body 2 is damaged, when the belt body 2 needs to be replaced, the toggle rod 305 is pulled outward at the same time, so that the toggle rod 305 drives the moving block 303 to move, and the moving block 303 drives the inserting block 304 to move and squeezes the spring 302, causing the spring 302 to deform. After the inserting block 304 is separated from the inner side of the insertion hole 8, the belt body 2 is pulled upward, so that the belt body 2 drives the inserting rod 7 to separate from the inner side of the slot 6, and the belt body 2 can be replaced. This prevents the inconvenience of replacing the belt body 2 when the belt body 2 is damaged, thereby reducing investment costs.
