[0025] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0026] Combined with appendix Figures 1-7 A self-sealing floating roof support for an oil tank includes an outer floating roof tank body 1, with a floating roof 2 slidably connected inside the outer floating roof tank body 1. Floating roof supports 3 are installed on the floating roof 2 at equal intervals. Each floating roof support 3 includes a sleeve component 301, a support tube component 302, a sealing gasket 303, a sealing bolt 304, and a sealing flange 305. The sleeve component 301 is located on and fixedly connected to the floating roof 2, and the support tube component 302 is installed inside the sleeve component 301. The bottom end of the support tube component 302 passes through the floating roof 2, and the bottom end of the support tube component 302 contacts the inner surface of the bottom end of the outer floating roof tank body 1. The top end of the sleeve component 301 is equipped with a sealing gasket 303 and a sealing flange 305. The sealing flange 305 is connected to the top end of the sleeve component 301 by a sealing bolt 304. The inner ring of the sealing gasket 303 contacts the outer wall of the support tube component 302. The sealing gasket 303 seals the gap between the sleeve component 301 and the support tube component 302.

[0027] The sleeve component 301 includes a sleeve 301.1, a pin bolt 301.2, and a pin nut 301.3. The outer wall of the sleeve 301.1 is provided with two communicating grooves, and the two communicating grooves are positioned correspondingly. The pin bolt 301.2 is slidably connected in the communicating groove, and the pin bolt 301.2 is in contact with the support tube component 302. The pin nut 301.3 is threadedly connected to one end of the pin bolt 301.2 that passes through the sleeve 301.1.

[0028] The top end of the sleeve 301.1 is provided with a connecting flange, and a sealing gasket 303 is placed on the connecting flange.

[0029] Sealing washers 303 are also provided between the pin nut 301.3 and the pin bolt 301.2 and the outer wall of the sleeve 301.1, respectively, and the two connecting grooves are sealed by the two sealing washers 303 respectively.

[0030] The outer wall of the pin bolt 301.2 is provided with a thread, and the rest of the pin bolt 301.2 is in a smooth state, which facilitates the tight contact between the sealing washer 303 and the outer wall of the pin bolt 301.2.

[0031] The support tube component 302 is provided with a through groove, and the position of the through groove corresponds to the position of the connecting groove on the sleeve 301.1. A pin bolt 301.2 is slidably connected in the through groove.

[0032] The sealing gasket 303 includes a gasket body 303.1, a positioning gasket 303.2, a tightening ring 303.3, and a tightening band 303.4. The positioning gasket 303.2 is fixedly connected to the upper surface of the gasket body 303.1, and the tightening band 303.4 is installed inside the positioning gasket 303.2. The tightening bands 303.4 are fixedly connected to each other by the tightening ring 303.3.

[0033] The positioning pad 303.2 is located on the pad body 303.1 near the inner ring. The positioning pad 303.2 limits the position of the tightening ring 303.3 so that the tightening ring 303.3 can cover the raised part of the pad body 303.1.

[0034] The positioning pad 303.2 is provided with equidistant mounting grooves, and a tightening strap 303.4 is installed in the mounting groove.

[0035] Both the tightening ring 303.3 and the tightening band 303.4 are made of elastic material. Through their own contraction characteristics, the tightening ring 303.3 and the tightening band 303.4 bring the inner ring of the gasket body 303.1 closer to the outer wall of the support tube component 302. The elasticity of the tightening ring 303.3 and the tightening band 303.4 applies a pushing force to the inner ring of the gasket body 303.1, ensuring that the inner ring of the gasket body 303.1 is tightly pressed against the support tube component 302. When the outer wall of the 02 support tube component 302 comes into contact with the bottom of the outer floating roof tank body 1, it will generate a certain degree of vibration. The vibration of the support tube component 302 will be transmitted to the gasket body 303.1, generating a certain degree of friction. The friction will cause a certain degree of wear on the gasket body 303.1, reducing the sealing performance of the gasket body 303.1. The tightening ring 303.3 and tightening band 303.4 apply a thrust to the worn gasket body 303.1.

[0036] In the aforementioned self-sealing floating roof support for oil tanks, during use, the operator inserts the support tube component 302 into the sleeve 301.1 located on the floating roof 2, and fixes the support tube component 302 into the sleeve 301.1 using a pin nut 301.3 and a pin bolt 301.2. Then, a gasket body 303.1 is fitted onto the support tube component 302. The inner ring of the gasket body 303.1 will lift at the contact point with the support tube component 302. The lifting portion of the gasket body 303.1 is then pressed tightly against the support tube using a tightening ring 303.3 and a tightening strap 303.4. The outer wall of component 302, and the lower surface of gasket body 303.1, will contact the connecting flange on sleeve 301.1, and the sealing flange 305 will be placed on the upper surface of gasket body 303.1. The sealing flange 305 and the connecting flange will be connected by sealing bolt 304, which will limit the position of gasket body 303.1. The gasket body 303.1 will seal the gap between the outer wall of support pipe component 302 and the inner wall of sleeve 301.1, preventing oil and gas from leaking out from the gap between the outer wall of support pipe component 302 and the inner wall of sleeve 301.1.
