[0024] In the embodiment of the present application, by providing an inner floating disc that is convenient for assembly, the above device effectively solves the problem that when installing the floating pipe, the screw holes on the connecting plates of adjacent two floating cylinders need to be aligned one by one and connected by bolts, and then the screw holes on the floating cylinder connecting plate are aligned with the screw holes opened at the corresponding positions on the inner ring beam or the outer ring beam, and then fastened and connected with bolts. This requires a very high precision for aligning the screw holes, and after alignment, tools are needed to screw the bolts, with many operation steps, which affects the installation efficiency. When installing the floating pipe body, the round rod is pulled outwards. After the round rod is stretched to the top, it is screwed 90 degrees. The rectangular block is limited by the limit groove, and the floating pipe body is clamped on the block. The block applies a limit to the floating pipe body to prevent rotation. The round rod is screwed 90 degrees in the reverse direction to reset. At this time, the round rod is released, and under the action of the spring, the round rod slides inwards and extends into the floating pipe body to limit and fix it. Only by pulling and screwing the round rod can the installation operation be completed, without the need to additionally use tools for installation. The operation is simple and convenient, which is beneficial to improving the installation efficiency. Embodiment

[0025] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the technical problem that when the above-mentioned device installs the floating pipe, it is necessary to align the screw holes on the connecting plates of adjacent two floating barrels one by one and connect them with bolts, and then align the screw holes on the floating barrel connecting plate with the screw holes opened at the corresponding positions on the inner ring beam or the outer ring beam, and then fasten and connect them with bolts. This requires a very high precision for aligning the screw holes, and after alignment, tools are needed to screw the bolts, and the operation steps are numerous, which affects the installation efficiency. The general idea is as follows: An inner floating roof that is convenient for assembly, including an inner floating roof body 11, a clamping block 12 is fixedly connected to the inner wall of the inner floating roof body 11, a floating pipe body 13 is clamped to the outer surface of the clamping block 12, a round rod 14 is slidably connected to the inside of the inner floating roof body 11, a spring 15 is sleeved on the outer surface of the round rod 14, the spring 15 is sleeved inside the inner floating roof body 11, a limiting groove 16 is opened inside the inner floating roof body 11, and a limiting mechanism is fixedly connected to the inside of the round rod 14. The limiting mechanism includes a rectangular block 17, the rectangular block 17 is fixedly connected to the inside of the round rod 14, and the rectangular block 17 is adapted to the limiting groove 16. When installing the floating pipe body 13, the round rod 14 is pulled outwards. After the round rod 14 is stretched to the top, it is rotated by 90 degrees. The rectangular block 17 is limited by the limiting groove 16, and the floating pipe body 13 is clamped on the clamping block 12. The clamping block 12 applies a limit to the floating pipe body 13 to prevent rotation. The round rod 14 is rotated 90 degrees in the reverse direction to reset. At this time, the round rod 14 is released, and under the action of the spring 15, the round rod 14 slides inwards and extends into the floating pipe body 13 to limit and fix it. Only by pulling and screwing the round rod 14 can the installation operation be completed, without the need to additionally use tools for installation. The operation is simple and convenient, which is beneficial to improving the installation efficiency.

[0026] A first hinge 18 is fixedly connected to the lower end of the inner floating roof body 11. A second hinge 19 is rotatably connected to the inside of the first hinge 18. A support rod 21 is fixedly connected to the lower end of the second hinge 19. The support rod 21 and the inner floating roof body 11 are on the same vertical line. The floating pipe body 13 is installed on the inner floating roof body 11. The floating pipe body 13 increases the buoyancy of the inner floating roof body 11. The inner floating roof body 11 is placed in an oil barrel, and the inner floating roof body 11 is supported by the support rod 21. As the liquid level rises and falls, the inner floating roof body 11 will also move up and down accordingly, so as to detect the change of the liquid level and reduce the evaporation of the liquid.

[0027] A tension spring 22 is sleeved inside the second hinge 19. A limiting rod 23 is rotatably connected inside the second hinge 19. The limiting rod 23 is sleeved on the inner surface of the tension spring 22. A pressing plate 24 is fixedly connected to the outer surface of the limiting rod 23.

When the support rod 21 is installed, it is clamped in the clamping groove 25 by the limiting rod 23 to ensure the stability of the support rod 21 during support.

[0028] Aiming at the problems existing in the prior art, the utility model provides an inner floating disc that is convenient for assembly. When installing the floating pipe body 13, the round rod 14 is pulled outwards. After the round rod 14 is stretched to the top, it is rotated by 90 degrees.

Only by pulling and rotating the round rod 14 can the installation operation be completed, without the need to additionally use tools for installation. The operation is simple and convenient, which is beneficial to improving the installation efficiency.

[0029] Working principle:

[0030] In the first step, the floating pipe body 13 is installed on the inner floating disc body 11. The floating pipe body 13 increases the buoyancy of the inner floating disc body 11. The inner floating disc body 11 is placed in an oil barrel, and the inner floating disc body 11 is supported by the support rod 21. As the liquid level rises and falls, the inner floating disc body 11 will also move up and down accordingly, thereby detecting the change in the liquid level and reducing the evaporation of the liquid.

[0031] Second step, when installing the floating pipe body 13, pull the round rod 14 outwards. After the round rod 14 is stretched to the top, rotate it by ninety degrees. Limit the rectangular block 17 through the limit groove 16, and snap the floating pipe body 13 onto the clamping block 12. Apply a limit to the floating pipe body 13 through the clamping block 12 to prevent rotation. Rotate the round rod 14 ninety degrees in the reverse direction to reset. At this time, release the round rod 14, and drive the round rod 14 to slide inwards into the floating pipe body 13 under the action of the spring 15 to limit and fix it. Just pull and rotate the round rod 14 to complete the installation operation, without the need to additionally use tools for installation. The operation is simple and convenient, which is beneficial to improving the installation efficiency. When it is necessary to carry and move the inner floating tray body 11, press the pressing plate 24 to drive the limit rod 23 to be removed from the card slot 25. At this time, without the limit of the limit rod 23, the second hinge 19 can be rotated to drive the support rod 21 to rotate and contract, reducing the occupied area during handling, which is beneficial to improving the flexibility of the device. When the support rod 21 is installed, it is clamped in the card slot 25 through the limit rod 23 to ensure the stability of the support rod 21 during support.
