Description

Technical Field

[0001] The utility model relates to the technical field of storage tank floating plates, in particular to a high-stability internal floating roof storage tank floating plate installation device. Background Art

[0002] The floating plate is an energy-saving and environmentally friendly device that covers the liquid surface and rises and falls with the liquid level of the storage tank through buoyancy. In order to reduce the evaporation loss of liquid oil in the storage tank and prevent the liquid oil from being polluted and deteriorated by various factors in the atmosphere such as rain, snow, and sand, a floating plate is usually installed in the storage tank, and the floating plate floats on the surface of the liquid oil. The traditional steel floating plate is assembled from multiple pieces, so a card is set between adjacent floating plate units, and multiple floating plate units are spliced ​​by multiple card pieces. In order to prevent the floating plate from sinking to the bottom of the storage tank, a support rod is set at the bottom of the floating plate. In order to prevent the floating plate from rotating around itself, an anti-rotation cable is set in the storage tank, and the anti-rotation cable runs through the floating plate. In order to conduct static electricity on the floating plate in time, a conductive cable is installed on the floating plate.

[0003] According to patent publication number CN113548324B, a high-stability internal floating roof storage tank float is provided, which belongs to the technical field of storage tank floats, and includes: a sealing pad, a clamping assembly, an air guide pipe, a limit pipe and a conductive rope. The air guide pipe is installed on the clamping assembly, and the air inlet end of the air guide pipe extends to the bottom of the clamping assembly for exporting oil and gas. The top of the limit pipe is fixed on the storage tank, and the limit pipe sleeve is arranged on the air guide pipe. The limit pipe is used to export the oil and gas in the air guide pipe, and the limit pipe cooperates with the air guide pipe to limit the freedom of the sealing pad to rotate around its own axis. One end of the conductive rope extends to the bottom of the clamping assembly for exporting static electricity, and the other end of the conductive rope is connected to a motor for transmission, and the conductive rope is used to drag the sealing pad with the help of the motor. A high-stability internal floating roof storage tank float provided by the present invention realizes the functions of preventing rotation, exporting static electricity, dragging sealing pads, blocking storage tanks and exporting oil and gas, and the components required to be installed are relatively few and the level of integration is relatively high, which reduces the operation and maintenance costs. The following problems exist in the prior art:

[0004] The floating plate in the current internal floating roof storage tank is relatively large, which makes it difficult for operators to install the floating plate. The large size leads to poor sealing performance. At the same time, the bottom of the current floating plate contacts the ground after being assembled on the ground, so that dirt and dust are adhered to the bottom, which makes it impossible to clean the bottom. As a result, the floating plate is directly lifted by a crane and assembled with the storage tank without paying attention, causing the dust at the bottom of the floating plate to be brought into the storage tank.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, the utility model provides a floating plate installation device for a high-stability internal floating roof storage tank, comprising a storage tank body 1 and a storage tank cover 2, wherein a conical surface is arranged above the outer surface of the storage tank cover 2, a ventilation hole 3 communicating with the inside and outside is opened in the middle of the upper surface of the storage tank cover 2, a ground wire connection hole 4 communicating with the inside and outside is opened on the conical surface of the storage tank cover 2, a liquid level gauge conduit 5 is arranged inside the storage tank body 1, and the upper surface of the liquid level gauge conduit 5 penetrates through the outside of the conical surface of the storage tank cover 2 and is fixedly connected, and a liquid level gauge 6 is fixed on the upper end of the liquid level gauge conduit 5;

[0027] The arrangement of the liquid level gauge conduit 5 and the liquid level gauge 6 makes it easy to observe the amount of liquid in the storage tank body 1, and the arrangement of the ventilation hole 3 facilitates ventilation.

[0028] like Figure 2 - Figure 3 As shown, the lower end of the liquid level gauge conduit 5 is fixedly connected to the lower surface of the inner wall of the tank body 1, and the inner wall of the tank body 1 is provided with four limiting grooves 11 in an annular array. The inner wall of the tank body 1 is provided with a floating plate 13, and a sealing ring 12 is fixedly connected below the outer surface of the floating plate 13, and the outer surface of the sealing ring 12 overlaps the inner wall of the tank body 1. A limiting assembly 14 is fixedly connected above the outer surface of the floating plate 13, and the limiting assembly 14 includes a fixing ring 141, and the outer surface of the fixing ring 141 is fixedly connected to four rubber limiting blocks 142 in an annular array, and the outer surfaces of the four rubber limiting blocks 142 are slidably connected to the inside of the limiting groove 11, and the outer surface of the fixing ring 141 is fixedly connected to four arcuate sealing strips 143 in an annular array, and the outer surfaces of the four arcuate sealing strips 143 overlap the inner wall of the tank body 1;

[0029] When it is necessary to install the floating plate 13, the assembled floating plate 13 is lifted by a crane and placed directly above the storage tank body 1, and then the rubber limit blocks 142 in the fixing ring 141 are respectively placed in the corresponding limit grooves 11, so that the floating plate 13 is slowly lowered and enters the storage tank body 1. Since the rubber limit blocks 142 have a certain ductility, the rubber limit blocks 142 are tightly fitted with the inner wall of the limit groove 11 when the floating plate 13 moves up and down, thereby preventing leakage from the gap. When the floating plate 13 is placed, the sealing ring 12 is tightly fitted with the inner wall of the storage tank body 1, thereby achieving a primary seal. The arc-shaped sealing strip 143 is provided to achieve a secondary seal. After the floating plate is installed, the storage tank body 1 is installed and fixed by the storage tank cover 2, and then the feeding diffusion pipe 8 is provided to facilitate the liquid to enter the interior of the storage tank body 1.

[0030] like Figure 4 - Figure 5 As shown, a U-shaped electrostatic derivation plate 131 is fixedly connected to the front and rear sides of the upper surface of the floating plate 13, a through hole 132 is opened at the rear right side of the upper surface of the floating plate 13, the interior of the through hole 132 overlaps the outer surface of the liquid level gauge conduit 5, a rotating shaft 133 is movably connected through the middle of the upper surface of the floating plate 13, a rotating plate 134 is fixedly connected to the upper end of the rotating shaft 133, a circular stopper 135 is fixedly connected above the outer surface of the rotating shaft 133, the lower surface of the circular stopper 135 overlaps the upper surface of the floating plate 13, and the rotating shaft 133 is connected to the upper surface of the floating plate 13.

[0031] When the floating plate 13 is assembled on the ground, the rotating shaft 133 is driven to move by rotating the rotating disk 134, so that the connecting plate 1331 and the scraper bar 1332 are rotated, so as to scrape the dust on the lower surface of the floating plate 13. After the operation is completed, the operator uses tools to clean the dust on the edge of the floating plate 13 and the dust on the surface of the support rod 136 and the buffer block 137. The setting of the support rod 136 prevents the bottom of the floating plate 13 from colliding with the bottom of the inner wall of the tank body 1. The setting of the U-shaped static electricity lead-out plate 131 and the conductive rope prevents the generation of static electricity, which has a protective effect.

[0032] The working principle of the floating plate installation device of the high stability internal floating roof storage tank is described in detail below.

[0033] When the floating plate 13 is assembled on the ground, the rotating shaft 133 is driven to move by rotating the rotating disk 134, so that the connecting plate 1331 and the scraper strip 1332 are rotated, so that the dust on the lower surface of the floating plate 13 is scraped off, and then the floating plate 13 is placed in the tank body 1 by the setting of the crane, so that the rubber limit block 142 slides downward inside the limit groove 11, thereby facilitating the installation of the floating plate 13, and the sealing ring 12 and the arc-shaped sealing strip 143 are set to achieve a sealing effect.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
