Embodiment 1

[0031] Please refer to the accompanying drawings, the present invention provides a technical solution: a double-sealed floating plate, including a floating plate 1 and an oil storage tank 2, the floating plate 1 is located in the oil storage tank 2, and the right side of the bottom surface of the oil storage tank 2 is fixedly connected with an outlet The oil pipe 16 is also provided with an air vent 6 and an oil measuring hole 7 on the top surface, and an inflation valve 5 with a valve is communicated with the middle of the top surface of the floating plate 1. The inside of the floating plate 1 is provided with a cavity 35, and the cavity 35 Airbags 15 are fixed on the edge of the periphery, and several support rods 3 are fixed on the bottom surface of the floating plate 1. Several pressure rods 17 are hinged above the top surface of the floating plate 1. A chute 18 is arranged on the inner side of the pressure rod 17, and the upper end is hinged. There is a fixed block 19, a N...

Embodiment 2

[0041] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the pressure assembly includes a lower pressure rod 23 hinged on the top surface of the floating plate 1, and the top end of the lower pressure rod 23 abuts in the chute 18, and the hinged part No. 2 torsion spring 36 is provided.

[0042] The second torsion spring 26 drives the lower pressure rod 23 to rotate downward, so as to ensure that the lower pressure rod 23 is always in contact with the chute 18 of the pressure rod 17, and ensure that the sealing block 21 and the sealing skin 22 are always attached to the oil storage tank 2 on the inner side.

Embodiment 3

[0044] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the positioning assembly includes a protruding rod 30 fixed at the edge of the bottom surface of the floating plate 1, and a sliding rod 31 is fixed on the outer wall of the protruding rod 30. The sliding rod The outer end of 31 is slidably connected with sliding frame 33, and the end of sliding bar 31 that is positioned at sliding frame 33 is provided with No. 2 spring 32, and the outer end of sliding frame 33 is rotatably connected with positioning wheel 34.

[0045] When the floating plate 1 moves up and down in the oil storage tank 2, under the action of the No. Move up and down in the vertical direction to avoid tilting of the floating plate 1 and affect the working effect of the floating plate 1.

Abstract

The invention discloses a double-seal floating disc in the technical field of floating discs. The double-seal floating disc comprises a floating disc, wherein the floating disc is located in an oil storage tank, the top surface of the oil storage tank is provided with an air hole, an oil measuring hole and a light hole, the floating disc is provided with an inflation door, a cavity is formed in the floating disc, and air bags are arranged on the periphery of the floating disc, and the floating disc is provided with a pressure assembly, a positioning assembly and a static exporting assembly. Through the pressure assembly and the air bags, the floating disc is internally inflated through an inflation door, so that the air bags on the side face of the floating disc are expanded, holes in the floating disc and the side face of an oil storage tank are filled, primary sealing is conducted, a rotating handle is rotated, a rotating frame moves outwards along threads on a threaded pipe, an ejector rod is driven to move rightwards, and the ejector rod presses a pressure rod; a fixing block drives a sealing block and a sealing skin to be tightly attached to the inner side wall of the oil storage tank, the sealing skin and the sealing block form secondary sealing, the sealing effect of the device is enhanced through the secondary sealing, and the situation that the working effect of the device is affected due to sinking or collapsing of the floating disc caused by oil immersion or oil gas leakage and volatilization is avoided.

Description

technical field [0001] The invention relates to the technical field of floating discs, in particular to a double-sealed floating disc. Background technique [0002] The floating plate in the storage tank is a kind of energy-saving and environmental protection equipment that covers the liquid surface by buoyancy to make it rise and fall with the liquid level of the storage tank. In order to reduce the volatilization of the medium in the storage tank, reduce loss, save energy, and protect the environment, an internal floating plate is added in the storage tank. The storage tank saves energy and protects the environment by installing a floating plate to seal the stored medium and reduce the temperature of the medium. This equipment is widely used in petrochemical units all over the country, major oil companies and refineries of Sinopec and PetroChina, ports, terminals, transportation, power plants and military logistics departments. [0003] According to whether there is a fi...
